I get this.  I was pretty pissed off  bout the Singer X-men movie.  A joke about the costumes?!?  Wolvie and Kitty in the original team?!?
I have come to accept that comic movies aren't (and should not be) exact copies.  Although Sin City was pretty good, and that was a fun experiment,.
Alan Moore said something about his comics being made into movies.  I cannot find the quote but it is, effectively, who cares?  If you give poop, read the book.
This hit me hard watching the first episode of "Locke and Key".  I ditched the show and devoured every issue of the comic.  You should too.
