OK Captain Devil's Advocate. I know Ironman is going to survive isolation in space. Doesn't detract one iota from any potential of my own enjoyment from the film. Every character here is defined by a comic book, has a more or less defined archetype with their undisclosed (or not) background, Devil is in the details.
Warlock was a critical player in the original story and won't even be mentioned here. Also, Thanos's dick was hard for Death, a character named after death itself, where he thought celebrating her with more "death" would seduce her, not a 50% life reduction to bring an arbitrary balance to the universe... Same characters, similar circumstances, completely different story. I mean, how many Batman origin'ish stories are out there. Some are good, some are terrible. Like Marvel films themselves...
All I read is "I'm not gonna watch Lion King cuz I've read Hamlet."
...
OK.
