There has been some awesome costumes/cgi costumes and some horrible, butt ugly, and split up costumes in comic book movies. These are the good ones! These are in NO SPECIFIC ORDER of quality!
1: Hell Boy!:
It looks amazing and accurate. Except the hand is reversed!
2: The Hulk!:
This Isn't a costume but it counts because it brings a comic book character to life! It looks great!
3: Ben Affleck Batman!:
It doesn't matter what you think about batsman vs superman it Ben Affleck, this suit is incredible! It's also better and more accurate than any of the other batsuits!
4: Superman returns Superman!:
This is most accurate than any other suits. The original version was great but it's a weird spandex and Man of Steel one looks amazing, but does not have the trunks.
5: Silver Centurion!
Every one of the Iron Man suits looks amazing but the one that takes the cake is the Silver Centurion!
Just the comic book up above, oh wait that's the movie! Ha ha that's a good joke!
Amazing Costume, amazing actor, Amazing effects, Amazing movie!
8: Red Skull!
He looks really great, uhhh , I'm running out of jokes. Any way, we got 7 more of these.
The first accurate X men costume. But the 2nd one is...
He looks amazing and is the first huge (size wise) X-Men! He also sounds great!
11: The Violator!
It looks exactly the same! You disagree?! I'll kill you! Ahhhhh (I won't really kill you)
12: Andrew Garfield Spiderman suit!
The one from the 2nd Amazing spiderman, the first one looks like a yellow oil slick. The Toby magueyr(misspelled) suit looks amazing but this one is more comic accurate!
13: Ghost Rider spirit of Vengeance!
Again the 2nd one looks better than the ghost rider in the first movie! The first one looks like a paper ball on fire.
14: The Joker!
All of the Jokers so far look comic accurate! Huh, reverse Dr Doom!
15: Green Arrow!
If anything it's an improvement, he doesn't look like a pied piper!
