This aims to be Memento, but Nolan hasn't been able to produce anything with as much depth as Memento since his second film; I understand that would be difficult to do as I'm a huge fan of Nolan and Memento. This story however is extremely hallow and full of unnecessary action for the sake of action. This is pop corn; this is bubble gum. Inception doesn't come close to depths of Memento. This is a very good action/sci-fi movie, but not a great one at that. It was made to sell a lot of tickets and a lot of popcorn, but there is no other reason this film exists much beyond that. To try and pass this off as a deep film is an insult to many filmmakers that came before and are still around now. It's even an insult to Nolan's own Memento. This movie is based around a trick. And maybe it's even a good trick. Maybe it's not? But in the end, it feels like I watched this for the same reason I would do a crossword puzzle or a brain tease-to have an entertaining mental challenge for a brief moment, but this movie doesn't go much beyond that. I didn't care about the characters, if Nolan wanted me to care about these characters he would have spend more time with the characters, gone deeper into the relationship between DiCaprio and his wife, but instead he spent more time with silly mind tricks and mindless gunfights so that you'd spend more on popcorn. This movie insulted my intelligence by thinking that I'd be wooed by this empty, hallow mind trick.
