I was thinking about this a few days ago actually - when will we get a superhero movie without a villain? I don't mean that in the sense of, "oh, turns out the bad guy was actually sympathetic", I mean straight up no bad guy period. The hero is racing the clock, or fighting against the elements, or battling some inner-struggle, etc.
Im sure it can be done but would it really be that compelling? I mean we could have a movie about Superman saving the world from a meteor but wouldnt it be more compelling if there was some evil force trying to stop him? I would argue that for a 2 hour film, we need that villain.
