One of the best films I've seen in 10 years. If you have a hard time following complex plots, you might not get the full experience. This movie is both mentally stimulating and engaging, and filled with action and excitement. There is nothing else quite like it. Sure, there may be films based on dream worlds, but that's where the similarities end.
I expected it to suck. It met and exceeded my expectations! It starts out being so bad that it's good, then it gets worse and goes back to being terrible.
In all seriousness, the movie got off to a good start. Right around the time they get on the plane to leave the island is where it goes south. Cliche after terrible cliche, lines that could have been written by a hyperactive ten year-old, and over the top explosions and killing. If you don't like a movie to be engaging and mentally stimulating, and just want a testosterone and steroid packed action flick, this film is for you. Otherwise, go see Inception.
Sadly, this movie has already and will continue to make lots of money, lowering the bar and ushering in a new era of crappy movies. Please tell Hollywood that throwing together a bunch of big names and a half-assed script is not acceptable, by not seeing this movie.
