Went and checked this out earlier today. The trailer really looked good when I saw it earlier this year, and I've always enjoyed boxing movies personally.
I hate to say this, but this movie was a little boring for my taste. The acting was really good from all characters, and the story wasn't bad at all...I guess I just expected more intensity, and what I got was some intensity, but a lot of emotional baggage from the base line of the story (which is essentially a coming of age movie for both the dad and daughter). It wasn't over the top or anything, it just felt like they focused too much on the depression portion of him vs. the almost "revenge story" the movie, to me, should have been.
All in all, it was an ok movie, but I'd probably wait for Netflix before spending theater money on it.
