I think faithfulness is very important because im tired of hollywood screwing up comic book characters like venom, galactus, and deadpool just so they can say "oh hey we know we screwed up so lets make a spin off movie where we can get the characters right and milk more money from the fans". However if the director can make it work like with Iron Man or Watchmen or even The Dark Knight then i'll have no problem with it. Very rarely i will accept huge changes like transformers for example (which did take me a long while to accept), i hated what they did too the character designs and kept saying that it is possible for them to look closer too the G1 designs and still have that realistic presence on the big screen, im not saying megatron should be a gun but if you looked at some other incarnations of that character he still somewhat retained that G1 look in his robot mode. The reason why i end up liking it and loving the second one was (besides being a fan of the franchise for a long time) that i looked at the good side of things and that's finally seeing giant robots on the big screen but i still have hopes for a reboot. So far i have not seen anything too faithful from the G.I.Joe movie except the look of storm shadow and snake eyes, thank god they didn't change those 2 huh,lol, they could of easily altered their suits too the extreme and gave them different colors like green and purple too the point where they look unrecognizable too the source material. I can't imagine how fans would react too that but it does make me realize that most comic book movies have both faithfulness and unfaithfulness going on for them for example a comic book movie can get almost everything right in the story but when it comes down to one or more characters they can stay unfaithful as they can get and that can work the other way around too, everything else in the movie can be unfaithful except for key characters. Don't know if they are saving a more iconic cobra commander design for the sequel but its not just the look of the good ol' commander that's shunning me away from this movie, its just the fact that the film doesn't look or feel like G.I.Joe too me but who knows i might come around too it one day, as for now i hope things look better in the sequel or even a reboot if they choose that route.
