I was pretty pleased to find out that I enjoyed the 3rd movie when I saw it tonight. It was confusing at times and it made me think but that's how i like 'em. I was hooked. In my opinion, if you want a thrill ride then this is something you will want to see.
btw, I went to the movie for free. How? well, during the movie, the sound kept cutting in and out for like a few half seconds every five minutes. At the end of the movie, I asked for my money back and got it back.
