Good actor or not?

Solid. Funny thing is, I have more time for him now than when he was a major movie star. He's settled into the role of character actor with gravitas quite nicely. I'd definitely say good actor, even if some of his films are less than mediocre.

Good actor.

I'd say mediocre. I mean his fake southern accent (JFK-the fake conspiracy film) and fake Boston one (13 Days-- an okay one about the Cuban Missile Crisis) are pretty pathetic. He hasn't been in many good films, even though he won the Oscar for that boring one Dances with Wolves. Once he stooped to Waterworld it was all over for him as a serious actor.

He's a good actor in my opinion. He knows how to play the role given to him. There are bad actors out there who keep getting roles. He's not one of them.

He's limited. If the role fits his ability he does fine. But he's no Dustin Hoffman, or even Al Pacino.
He's a workman. He's okay.

He can be great. I had seen him in Dances With Wolves and Robin Hood, both fine films I felt he was good, little on the boring side. Then I watched Silverado and I didn't even recognize him at first, his performance was no energetic. I think his best performance is in No Way Out. He is fine in JFK. I also like Thirteen Days though why he even attempted such a bad accent is a mystery. No need for it.

GOOD...SOMETIMES GREAT...NEVER BAD.

Dunno, but without him there would be no dances with wolves - he first sheltered and then forced his friend to complete the script - and he directed it.

As far as his acting skills go - he's got limits. We all recall some actors do a role which doesn't fit their usual profile - al pacino, dustin hoffman, etc, but.... I haven't seen them nail too many other interesting roles since. Even Dustin Hoffman himself said that at the end of the day, all actors basically play themselves placed in different environments.
