Well, this is one of those movies that hinges on a singular performance. In this case it's Danny Glover who is absolutely amazing in his role, probably the best performance of his career, and one of the best that came out of the 80s. But Goldberg and Oprah really stink. I don't know what was going on there but they were all over the place. However, despite them, Glover does carry the role, and Spielberg realized that this was a film adapted from a play. He kind of took that and ran with it, so the performances (minus two notable ones) were as earnest as you would get in live theater, the set designs, the camera movements, it all felt less like a movie and a lot more like, well, like you were seeing it live on Broadway. And, honestly, I think that worked. It was a unique approach and it made it wonderful to watch.
