This film got a lot of praise for being so original. IMO, there really wasn't much in this movie that I hadn't already seen before in other movies, but the way they were put together in this film was pretty original. The main problem I had with this film is that it got really slow in the third act. That's also the act where Emily Blunt's character comes in. I just don't care for this actress. I have yet to see a movie of hers where I thought she was good. Admittedly, she was better in this movie than anything else of hers that I have seen, but I still don't care for her as an actress. The first 30-40 minutes of this movie were very strong in terms of cinematography, pacing, action, writing, dialogue, etc. Everyone but Emily Blunt was pretty good in terms of acting. The last 15 minutes or so was pretty good too. I didn't see the ending coming until about 5 minutes before it happened. I have a few more gripes about the movie, but they would get into spoiler territory. Still, I think the movie is definitely worth watching if you're a fan of sci-fi. It does suffer from the usual problems that all time travel movies deal with, but this movie did a pretty good job of trying to address those problems. 8/10 The fact that Rian Johnson both wrote and directed this movie makes me more excited for Star Wars Episode VIII: The Last Jedi.
