Since the current boom of comic book movies began with "Blade" in the late '90s, Marvel has pretty much ruled the roost. True, DC has the biggest single comic book box office hit in "The Dark Knight", but Marvel's films have been more consistently successful, and some of them, like "Iron Man" and the "Spider-Man" trilogy, have been mega-blockbuster smashes.
Still, Marvel's films have hardly been perfect. Sometimes, in an attempt to prepare a Marvel title for consumption by a non-comic-geek audience, liberties have been taken with characters to give them wider appeal or to help them fit into certain story lines. In short, here's a list of great Marvel comics characters who I think have gotten the shaft hardcore in Marvel's movies.

Dr. Doom.
Victor Von Doom's backstory in the comics is pretty compelling. Raised by gypsies, left orphaned by his mother, and burnt to a crisp in a lab accident. All of that was lost in the "Fantastic 4" movies in name of narrative economy. Instead, he gets to take a bath in cosmic rays during the incident that gives the Fan 4 their powers. Not as cool and getting blowed up, but I can understand that plenty of narrative issues that were eliminated by streamlining Doom's backstory. My problem is that the character in the movie ain't Victor Von Doom. Dr. Doom's a power-mad dictator who wants to take out Reed Richards, who he blames for causing the accident that put him in his metal suit. He's brilliant, single-minded, and quite vain. In the "Fan 4" movie, Doom' a guy who gets pissed at Reed Richards for stealing his girl (more on her later). That might make him more relatable to movie goers, but it also makes him so much less cool. Oh, one other thing: where the Hell were the DoomBots in the movies?! Dr. Doom ain't really Dr. Doom without DoomBots!!

Storm.
If you really stop and think about it, Storm's one of the most powerful members of the X-men. She controls the weather, thus making her capable of wide-spread devastation. In the "X-Men" movies, she's relegated to being a glorified wind machine. Sure, she takes out some jets with a forest of tornadoes in "X2", but most of her action is small-scale. Even worse, Halle Berry plays her in a way that doesn't leave much of an impression. Berry's a gorgeous woman, but she was in over her head in the X-movies. It's probably not much of a reach to say her wigs did more acting than she did. The writers didn't give her a ton of help. When your best line of dialogue is "Do you know what happens to a toad when it's struck by lightning?.. The same thing that happens to everything else.", you know you're gonna have to be a GREAT actor to sell your role. But that's what acting is: to elevate the words on the page to the point where the audience can buy that a real person would say those things. That's also what Berry fails to do. Most of the time, Storm just looks kinda lost.

The Lizard.
The Lizard was sure to show up in the Spider-Man movie universe sooner or later. A reference was made to Curt Connors in the first film. Then he actually showed up in "Spidey 2", played by Dylan Baker. He had an even bigger role in "Spidey 3", and it was obvious, given "Spidey" director Sam Raimi's love of old-school Spidey villains, that he was being set up to become an adversary in the very near future. 'Cuz that's just what happens to the science-minded folks in close proximity to Peter Parker. They have an accident, go apey, and before you can say "proportional strength of a spider", they're dangling Mary Jane off the top of a very tall building. Then, BANG!!, Sony executives decide to reboot the franchise, probably ruining any chance for us to see Baker play the full-on Lizard. It's a shame. He would have been awesome.

Gwen Stacy.
Let's stick with "Spider-Man" movies for a bit. It's hard to think of anyone in the Spidey universe who got shafted harder than Peter Parker's first love. First, the filmmakers took her personality (sweet, nice, caring) and gave it to Mary Jane in the movies. I'm fine with them honoring Gwen in that way, 'cuz at least she's in the movie in some capacity. But then, Gwen gets jammed into the third movie as part of a love triangle also including MJ and Peter. Worst of all, she's basically THE SAME CHARACTER as MJ in the movies. She's a sweet, pretty, nice girl, albeit one with one with a modeling gig and a need for science tutoring. The least they could have done was give her more than just her hair color to differentiate her from MJ.

Susan Storm aka The Invisible Woman.
Here's another case where casting may have sank the ship before it even launched. I dig Jessica Alba. She's beautiful and in the right role, she's a very effective actress. In a feat that astounded me to no end, she managed to out-act her bikini in "Into the Blue". All kidding aside, she was great in "Sin City" and she was the only thing worth watching in "Good Luck Chuck". And, man, does she look tasty in that blue Fan 4 uniform. But, Sue Storm isn't just a pretty face. She's a very strong, nurturing presence who's the glue that keeps the Fan 4 together. On top of that, she's very, very intelligent, as smart as her genius scientist husband. Alba just doesn't have a weighty enough presence to convincingly play someone like Sue Storm.

Venom.
Venom's a fan favorite for some reason. I've never been able to figure it out. He's basically Spidey on 'roids. I guess it probably has something to do with the fact that he has a bad-ass costume. Whatever. So, when it came time for "Spidey 3", Sony execs strong-armed Sam Raimi into including him. Sadly, Topher Grace was then cast, and the idea that he'd mirror Peter Parker was pretty good idea that didn't really pan out. The problem is really nothing more than Eddie Brock isn't developed well enough, he doesn't get enough time for us to really care about him, and he gets killed off in the end. Note to studio big-wigs: The multiple villain strategy really doesn't work.

Elektra.
I like Jennifer Garner. She's very pretty, very talented, and on "Alias" she proved she could kick copious quantities of ass. So, even though she wasn't the best fit for Elektra, who's an exotic, dark-haired Greek, and not the American girl-next-door, it seemed like it might work. And in "Daredevil", it actually did work. Elektra was the heart of that film. Well, apart from Jon Favreau's excellent portrayal of Foggy Nelson, that is. When it came time for an Elektra spin-off, the filmmakers stopped trying to do things that worked and started doing things that were safe. They gave Elektra motherly instincts and a Mini-Me tag-along. Hey, Fox Studios, "Elektra" ain't "Lone Wolf and Cub". Elektra comics are awesome because they're about an attractive woman in revealing attire kicking the stuffing out of ghost ninjas, hitmen, and whoever the Hell else gets in her way. If there was more of that in the movie, the character might have had a longer cinematic lifespan, and you might have made more green.

Deadpool.
Okay, this may be the queen-mother of Marvel movie character immolation. When Deadpool first shows up in "X-Men Origins: Wolverine", he's a witty, wise-crackin' ass-kicker played most excellently by Ryan Reynolds. The hopes of Deadpool fans everywhere soar. Then he disappears from the story, only to return as a colossal cluster-hump of a character misfire. Deadpool turns out to be an experiment in which scientists have combined the powers of multiple mutants in one body. So he can teleport, shoot energy beams out of his eyes, heal himself, and just for good measure, he has samurai sword jammed into his arms. But worst of all, his mouth is sealed shut. Okay, what part of "Merc with the Mouth" did the filmmakers not understand? Deadpool's most endearing quality is his smack-talk. And as my buddy Ryan has pointed out, if someone did manage to seal Deadpool's mouth shut, the first thing he'd do is find a way to open in back up again.
Note: I realise there are many folks out there that think Gambit got jobbed in the "Wolvie" movie. I didn't include him for two simple reasons: I'm tired of talking and I think Gambit's super-lame. The End.
