I'm really in trouble when I have to say anything about this movie.
First of all, forget about super cheesy and completely unpredictable story. If you are looking for this you should probably go look elsewhere.
Second, I kinda liked this movie. Although I had problems with character development: sometimes it doesn't really makes sense why a character does what he/she does. I felt that some scenes are over- acted and there is a character who doesn't succeed to fit his role at all.
I said that I kinda liked the movie and that's because it made me remember a girl who broke my heart a long time ago. I know that sounds strange but she had the exact same behavior as Jo has and I felt nostalgic when I was watching the movie. I made the same mistakes/efforts that Eric does and this really made me sad. A few days are already passed since I watched the movie but even if it's not the best movie I ever saw I still think about it a lot. The soundtrack is OK, I think Eric has a great voice ( I guess he's the one who actually sings ).
It was great that the viewer gets involved in the festival as well, I heard about Burning Man before but now I learned a few other infos about it.
Overall it's a nice movie with great soundtrack and scenery and you should definitely watch it if you were ever in love with someone.
