Was Robin Williams a good actor?

I wish I liked him more than I do because I am such a fan of Christopher Reeve and they were such good friends and Robin helped him out as much as anyone during a very hard time after his accident.

I did not like him in Good Will Hunting, which I really feel is a terrible film.

I did like his voice work in Aladdin, where his freestyling worked perfectly.

I have tried to watch Mork and Mindy but I just can't get into it.

I thought he perfectly cast as Popeye, a film that starts out with such promise but loses momentum.

In What Dreams May Come, a visual feast, he has his moments but not enough to recommend overall.

He's a very difficult actor to pin down as someone I like or dislike overall.

And then there is Hook, which again I think he had his moments.

But I enjoy his standup routines.

Dead Poet's Society showed me that he could do drama, reign in his 'comic' side.

I was very sad when he died, though.
