Inception was unquestionably the best movie I've ever seen in theaters. In fact, the only movie that has gotten close has been District 9. Inception was something else though.
First off, I'd just like to point out that Christopher Nolan is the best director today. He is great at creating suspense and can make a movie that the audience must pay attention to for the entire showing. They require actual thought throughout, but the idea is still explained without leaving too much confusion.
The acting in Inception was amazing. Joseph Gordon-Levitt gave the best performance, followed by Ellen Page. That's not to say the other actors weren't up to par, but these two deserve nominations. Ellen Page was especially notable. Not just because I love her (She reminds me of a good friend), but she was surrounded with great talent and shined. Just this movie alone should get her out of the Dramady genre that seemed to be what she was pegged in.
While special effects aren't really involved in my grade of a movie, I have to say that Inception blew me away here. I felt like I was in the dream world and that I could be an architect. When the city just started to bend in half, I just shook my head at how seamless it was.
As for actual content, Inception was even better. For every part that I was questioning, it was answered 10 minutes later. There was a very nice portion of action, but not too much that I was left wondering, "Where is the story?"
The pacing was occasionally off but never went too slow or fast, which is more impressive for being a 2 1/2 hour long movie. The ending, while I won't ruin it, was very nicely left open to interpretation.
All in all, this is easily the best movie of the year. With a nice mix of action and story, along with amazing performances, there is no reason why Inception shouldn't win an Oscar for best movie of the year, because I don't see any upcoming movie that should challenge it. It's already in my top 3 favorite movies of all time.
