I love comics and many of them I do consider "high art"
the problem is they LITERALLY just have to follow the damn panels. it's a friggin story board that is written out for them already. but so many writers and movie studios change dumb shit to "dumb it down" for the audience.
Primary example of which is the ending of the Watchmen. it's a fairly accurate adaptation UNTIL the end and it just spits in the face of the entire point of the damn comic. the ending is SUPPOSED to be ridiculous, it's SUPPOSED to be unbelievable. but for whatever reason they felt "nah, the audience won't get it"
This is also why i'm not optimistic about the upcoming Avengers movies. all they have to do is literally just follow the plot of the recent Secret Wars/Battle World comics. that's it. it's a good story, it sets up everything for them - future films and all that. but they won't.
Or the constant retelling of Batman. All you have to do is just follow one of the story arcs of whatever Batman comic. Do a killing joke movie, a hush movie, whatever. I no longer care about MORE versions of Year One.
