Morality tales are always difficult. Going after the whole fame makes one vulnerable thing too. Put "crazy fans" into it and you get something weird like this. And all that with one of the worst plans (if any) in recent memory. Things can go sideways and they will especially if you haven't really thought about them.
Don't get me wrong, there are quite a few scenes that are difficult to watch, because they are brutal and you feel the pain just watching. Nothing that is exciting or fun in any way. Thankfully it doesn't stay on that track too much. Not the kind of movies I like to watch anyway, this lacks a bit of empathy. Ryan Phillipe might feel at "home" (no pun intended) with some of the scenarios (job and fame wise that is), but this won't help him get back on any Hollywood radar any time soon
