I saw Inception and loved it. It took a concept which has been used fairly regularly (dream manipulation) and applied it in a fairly new and unique way. Although the overall plot is fairly twisting, it does a good job of explaining the "rules" to you without talking down to you. The action sequences were good, even though the movie was a little light on them despite what the trailers will have you believe. Overall its fairly plot driven without stuff blowing up every 10 minutes (although a fair amount of people shooting and each other does take place). Some of the characters are a little wooden, but I think they're supposed to be that way.
Overall I think its a great movie and is my favorite of the year so far. Two thumbs up.
