I thought the new Wampa shots looked pretty good. Mind you I'm not sure if they should have been added in or I would have placed them in that way. But it looks very realistic and not fake like the CGI Jabba.
Seriously since it was a guy in a suit, has anyone else noticed that a lot of the stuff in the prequels that still looks good was miniatures or other models? Even if just as much blue screen was used, I think a lot of effects would have looked so much better had they been photographing something real instead of CGI.
