I really enjoyed this. Obviously, they messed around with the chronology a bit, that's to be expected for pacing.
Kudos to the casting director for finding a really good Harley Race and a comically bad Ric Flair.
All the main characters did well in their roles and it was nice to see Maura Tierney again, who I hadn't seen for a while.
I think the brothers' reunion scene was meant to be Kevin's fantasy as he was looking down at Kerry's body. In Kevin's mind, Kerry was rowing up the river Styx (you even saw him laying out the tip) and was crossing over to be with the rest of the brothers.
Agreed on Mike being given more depth than the pro wrestling story usually gives him. That was a nice addition.
All in all, a really well done film.
