I still have no idea why Emma would sign on to a project like this... Maybe I don't know the gist of the script and it could turn out to be a great film but honestly, this doesn't seem like something that would make for that interesting of a movie.
To me, it seems to play out with America's whole idea of rewarding people for their bad behavior, such as making a film about it. This only occurred two years ago and in a time where anyone is given a reality show, I feel like it would only launch the people of the "Bling Ring's" careers into stardom. If the case was so fascinating, I think they should have waited at least a few years so that it would only stand as a film and nothing else. Of course, that's just my opinion and I don't know any of these people personally, so I suppose who am I to judge? Either way, I'm happy to see Emma working once again.
