I have to say it's tad over-rated. 4 stars perhaps, but 5? No.
The action sequences and CGI were not what I am looking for in the movie, but the subject matter (our subconscience and how our mind works). I was bit disappointed Nolan didn't dwell on it more.
"Juno" Paige was cute, but not yummy enough, and the 3rd Rock from the Sun kiddo put up a notable performance.
The 150 minutes flew past quickly for me which indicates it's a good enough movie.
