I think, if anything, Gunn's story has too much appreciation for comics - I think it was a bit of a barrier of entry to enjoying the film (there's so much going on).
Yeah, I guess in some ways, it's almost like seeing Star Wars for the first time; there's aliens, laser guns, robots and all kinds of weird shit going on in the background.
Superman had a lot of stuff going on in the movie, but it didn't turn into the exposition dump of Ayer's Suicide Squad movie, of spending the first half of the movie trying to introduce all these characters and extraneous characters, etc.
