Do you think that the bad adaptations of the past have contributed to the elaborate, yet not all that faithful costumes that we're seeing in movies? There's a small but vocal number of comic fans who complain about the armored Batsuits & raised webbing on Spider-Man's movie costumes. But I look back on the TV shows that we've had for these exact same characters, & I think part of the filmmakers' motive is to distance the movies from those shows as much as possible. If even the slightest visual reference calls to mind what we've seen before, they've failed.
Discuss.
Actually, I think most filmmakers strive to keep a comic-based film as close to the source material as possible. However, becaue they are different mediums, there's things in each that will and won't work. For example, Bryan Singer felt very strongly that a mass audience wouldn't accept the heroes and villains in brightly-colored spandex for a live-action film, especially one with such a contemporary storyline. So, in an effort to give the team a unified style, they all wore black gear, with unique aspects (Cyclops' visor, Wolverine's gloves, Storm's cape, etc.) included as nods to the classic staples.
Also, Singer said one of his beefs with the whole "X-Men" concept was the lack of any real "school setting" in the comics. His solution to that was to make some characters significantly younger than their illustrated counterparts (such as Rogue, Iceman, and Kitty Pryde). This would, in turn, allow him to present them as "new recruits" during future installments. It was a blod move, and I think it worked for the most part...but there were drawbacks as well (like having Mystique and Nightcrawler at roughly the same age in "X2", while in the comics she's his mother).
In the end, it all comes down to the fundamental differences between comics and film. The first is primarily visually-based, and because of that, there's not much restriction placed on the stories...you could draw practically anything, after all.
But with film, there's all sorts of rules, boundaries and limits which don't exist with the written word. From the shooting and lighting, to camera angles, ADR recording, music scores, sound and video effects...it becomes a huge jigsaw puzzle, and everyone has their opinion. As a result, the films often retain the "essence" of the original creations, but many specifics are either altered or trashed completely (for various reasons).
