I haven't seen the new Ghostbusters, so I don't have any firm opinions, though I understand that it's become something of a feminist touchstone, what with the new female cast. I'm a little nervous about its prospects though, on the basis of the trailers I've seen which aren't even slightly funny.
My kids must have been perhaps 4 and 6 when we got the original Ghostbusters video. They immediately became transfixed, insisting on watching it every day if we would let them. So I've seen it several dozen or perhaps even hundreds of times. I became convinced that it was a true masterpiece, an all but perfect mix of scary, funny and sensual. The deadpan humor of Murray, Aykroyd, and Ramis was critical, as was Reitman's directorial touch. The rest of the cast was also great.
My favorite line: "Back off man, I'm a scientist."
