Here's the problem. Other films have done this 'music is the centre of our relationship' schtick before and done in way better. Think, Hi-fidelity or Nick and Nora's Infinite Playlist then take away all the heart and the drama and the characters and the comedy and, well, just any interesting stuff that makes a film interesting to watch, and, boom, you have The Greatest Hits.
Then after all of that, set it in LA, have it poorly acted with everyone trying to be really rad, cool and/or laid back and go to do 'cool' LA things (silent disco, driving around in a vintage convertible in LA.....when has that ever been fun)
