I really did like it. The music is good throughout the movie. Fun references here and there. The director seems like he had fun in the making. It might seem all over place, that's cause it's so obviously a debut.
After IMDBing the movie, the director Marc Webb had only made 3 music documentaries, and a short before this first feature length fictional film. It all seems overcharged with everything a film-student usually likes to try in his first movie. That's why the un-perfection of the film, made it easier for us to identify with the characters. Specially in the 20s years, when all our decisions are known to have major impacts on the future, and when many failures are bound to present themselves along the way.
