You guys think film critics are trashing this movie because it doesn't have enough action? Like film critics put a premium on action or something? The reasons given are that the film is very poorly constructed, has very little in the way of interesting character interaction or progression, has a lot of bad exposition, and has a bad ending.
Everyone should decide for themselves, of course--I disagree with the critics to some degree about a movie like Mortal Engines, for instance. But a lot of people were excited for this film--not because they were hoping for some sort of action-filled M Night spin on a Marvel movie or something, but because they were actually hoping for a conclusion that fulfilled the promise of bringing Unbreakable and Split together--and a lot of those people are coming away disappointed. They're not writing the movie off just to write it off.
