I have a feeling it was kind of a miss on the "rock bottom" part though. I mean, guy has an uber-rich and hot ex-wife who still likes him (although not loves him), and like those typical stories do he "just can't accept her money" because he has to do it himself. Nice safety net! Then he sets off on this journey after hitting that "rock bottom" which basically consists of quitting his job and getting humiliated in public -- let's not forget that his humiliation and the ensuing popularity it got him is what gave him the possibility of coming back in the first place since he was famous now. I mean, at some point he sure had it pretty bad but nothing I would call "Rock Bottom", especially with that safety net.
I also just can't help but feel things just go way toooo easy on him once his project starts. It's like he's living in this fairy tale world where if you put in some hard work and shift the momentum, everything will magically fall into place and your efforts will be rewarded, almost without limits (at least for him).
The whole story just felt forced to me. It was a nice movie overall with some pretty good performances, but that's all it was in my opinion. I'd give it a 7
