Considering your current avatar and signature and how grossly inferior the MCU is to the comic books that spawned them, I find this kinda ironic...not that I disagree, but just saying.
Because I have a Star Lord set doesn't mean I'm into Marvel. I don't care about the MCU at all, or really comic books in general. I just like the Guardians films because they're fun standalone movies.
And I also know even the MCU takes extreme liberties with its source material; Guardians being the biggest example, but they're all trying to be a new thing, for the most part. They take some story beats from comics, but they're a new thing with a new goal for these movies, with the same general idea and characters.
Something like Avatar TLA vs the The Last Airbender film isn't trying to be anything but a straighton adaptation to me, with just an inferior genre to attempt it in. The characters, settings, story beats, etc, they are all just poorer carbon copies of the original. In my mentality, why do it at all? It's only going to be a letdown, and pretty much doomed to fail.
Thing is, I don't think adaptations are even a bad thing at all. Sometimes a whole scene just works better in the different language of a new medium, or a stale old idea gets revamped and works way better.
And even something like Avatar could have worked as a movie, someway. Definitely not in M. Night's hands, but who knows how it could've been for anyone else.
My point was really, I don't get the urgent want of people craving an adaptation of something that's already there to enjoy.
I get in this day and age we're weened to expect more of everything we love, with sequels and all that, but for me, I'm more than happy simply enjoying something that exists one way. It'll always be there to revisit to remind me why I love it.
If I love a video game, it can stay just that. I don't need to see it as a movie. I don't crave to see it as one.
If someone made it and it turned out to be good, I'd check it out and maybe like that one too; be pleasantly surprised, but I never begged for it.
That's more what I was getting at.
And with Guardians, I told you, I never read the source material, haha. I just found two movies I liked, and actually liked more because they weren't so heavily entwined with the rest of the comic cinematic universe I really don't care about.
