Comic books should be the easiest to translate into a film, as they are partially a visual medium. Now, that being said, movies, books, comics, poems, songs, sculpture, etc., are all different, and cannot be completely translated, no matter how good. But, it things can cross-over, and do very well in their own rights, so long as the artist knows what she/he/it is doing.

Here's to hoping Matthew Vaughn and Jane Goldman (screenplay) got it, 'cos this has potential to be quite entertaining.
