Mark don't get in a dander
I happen to have many posts praising Stallone, and if you read the rest of my comments, I didn't give De Niro a free ride either. Rocky was very good acting, especially for a new commer. And in Copland he does a great job.
Dolph does a good job in this movie but like some of the other actors mentioned even though they may not be a Brando or Olivier (both of whom I think are overated) there are certain roles only Sly can play and same for Dolph.
As far as this movie goes, check it out if you haven't seen it. Like I said, over look some of the low production value items and I think people may really like it.
