It's a brilliant film and is far deeper than just 'boxing'. I saw it on pirate well before it was out, and I was on the edge of my seat. It was gripping, I don;t think I've ever been like that even watching real fights!
I don;t see why people disliked Rocky V, I loved it, I thought it was a really deep film about a man looking to re-live his dreams through a guy who he wished was his son, which caused him to neglect his own family. It was also a great tale of how money has eaten up the sport. Plus, it had the best ending.
