The good:
It's a musical. They sing. A lot. It's both artsy and fartsy and that makes the film interesting and compelling in ways that augment the storyline.
The bad.
The story needs to be augmented. Or maybe disguised. There were lots of occasions I found myself asking "Why is he/she doing that?" or just scratching my head at some obvious distraction. She's playing an opera singer but it's clear she's not singing. He's a comedian but his act isn't in the least bit humorous.
