Captain America: Civil War is a 2016 superhero film. It is what you'd expect, so if you like that kind of thing you'll like this. I like that kind of thing.
The NYT calls it a "very crowded, reasonably enjoyable installment in the Avengers cycle" and says, "“Captain America: Civil War” does not in any way transcend the conventions of the genre. On the contrary: It succeeds because it doesn’t really try." Slash Film says it's "a sharp, astounding, action-packed summer blockbuster that’s the kind of superhero movie you’ve been waiting to see your whole life."
Roger Ebert's site gives it 3 out of 4 stars and says, "this is a satisfying film that takes its characters but not itself seriously, and mixes sequences of wonder, visual wit and pathos in with the world-building and dramatic housekeeping." Rotten Tomatoes has a critics score of 90%.
