The surprising and unsolicited fourth film had some promise in the first third of the film - I loved how it subverted expectations and was a meta deconstruction of the series itself. After the provocative and almost blasphemous setup, the film quickly devolved into poor action, weird pacing, and overall bad plot and character arcs. In a word, it felt senile. (The action shouldn't have been that bad with Keanu helming John Wick. It was just laziness.) The denouement was just same-y slop we see in every other dialed in action movie. Such a letdown for such a shocking cold open.
If you haven't seen the fourth film, it's a bit of a mind fuck. But turn it off the minute the reveal is over. That part is a treat, but it isn't worth your time otherwise.
