I did not like this movie at all. I have seen the show and I love it, but this movie was awfull. I could not connect with the characters at all and I didn't feel any emotion while watching this except annoyance. The music was good and it was the same music that is in the show. The voice actors did a good job as well. The story did not make a lot of sense. If I had not seen the show before hand I think that I would have been utterly lost. The characters were off the story was disjointed and confusing. It time jumped a lot as well. Overall I would not reccomend this movie.
