Enjoyed it a lot
Boxing films are a treat to watch, simply because boxing is such a taxing sport. Filming boxing scenes are really tricky, because it needs to be realistic and it needs to be convicting. In both instances, it worked. The camera work was great.
The acting was really good. The dysfunctional relationships, and the eventual coming together, worked really well, and felt honest and real.
All in all a very good film.
