Quick, entertaining, and interesting, but a little excessive.
These trailers were really lame so I had no interest in this until I saw the highly surprisingly positive reviews. I had no expectations so I guess those nonexistent expectations were surpassed, if you're going just by how this film is marketed. It looks tired and boring, and while it is derivative to a rather high degree, it's also pretty entertaining. There's a lot of humor and a bit of self-awareness which helps a ton, and Tom Cruise is good. I've heard people talking about how Emily Blunt owns this movie, but really, she's just as good as Cruise if not better, but probably because she's more straight-laced of a character in a way. The film never feels repetitive, ironically, since its editing is so tightly done. Nothing feels like fluff since something new is always happening. However, the third act feels like the second act was just stretched out and given this sort of narrative structure where one event is replayed increasingly differently over and over, it would be so incredibly easy to shorten the duration by removing some scenes or blending them together. Also due to the narrative structure is the problem that the resolution is predictable. It actually seemed to divert from what I thought would happen, but then it takes a cop-out that defies the mythology that has already been established. Compared to the trailers and how they only make it seem another tiresome Tom Cruise vehicle, it's great. Compared to movies in general or on its own terms, it's fine. Forgettable, but involving, if a little excessive towards the end. 7.2/10, good, one thumb up, above average, etc.
