My only thoughts on it: if a guy who films a live action intro to The Real Ghostbusters can get a girlfriend, then there must be some hope for me! (Not to insult anyone, though: how much hope is debatable. I might sound mean, but I'm actually quite happy for said Ghosthead.)
Also, I kind of thought the “ghost” effects in it were somewhat Pythonesque, a bit too Terry Gilliam. Stay Puft was quite good, though.
Pretty cool, but I didn't like it just because it was a bit shocking to see it done in live action. I'm just used to the animated intro, I guess. (But the animation to live action segue at the beginning was genius.)
