I watched Ghostbusters on BD over the weekend. What a great movie. Loved the Slimer mode picture-in-picture feature, it's one of the more entertaining ones I've seen.
Despite all the horror stories I've been reading about the amount of grain in the picture, with the Theatre mode on my Sony D3000 HDTV I can't say I really noticed it when I watched in on my Sony BDP-S350 player. Even though I knew it was there, I never once found it distracting and within a few minutes of watching it I was even thinking about it. The picture quality looked a lot better than I expected, facial detail was excellent, you could see every pitted pore on Bill Murray's face for example, and colours looked natural. The picture quality by no means reference material but it's the best I've ever seen it on DVD or TV. I'm happy.
I did try the movie on my PS3 and even with the same Theatre mode enabled, the grain was a little more obvious, especially when chapter skipping as the picture would freeze for a split-second. Sorry if that like a promotion for Sony products but I like their stuff!
The extras are good overall, the aforementioned Slimer mode being by far the best, as the others are a bit on the short side. One disappointment was the omission of the Ray Parker Jr. "Ghostbusters" video.
