I expected much more from this movie. For starters, there was no plot line that ended up developing anywhere. Also, little music was played to emphasize how important it was to the festival! (Having Jonathan Groff's character say "yeah man, music is life" does not qualify!) Overall, the movie was a fail. It put hippies into a generic stereotype along with jewish parents. I would rather watch the original concert DVD.
I liked the movie as a movie in general, but as a movie in the Harry Potter series, it was disappointing. The movie lacked suspense and fighting, and focused more on humor and romance. Although I enjoyed the humor, I think more action scenes should have been incorporated. Also, the ending to the movie wa weak. All in all, I do not believe that this movie was the best of the series and I would not see it more than once.
