For all the bitching about this movie, I have heard some legitimate praise. But before I say anything, no, I have NOT seen this movie.
Anyway, Erik Nagel is a huge nerd culture fanboi, and he got a chance to see the movie before it was released. He hated it from the start because of the trailer, but said that it actually wasn't a bad movie. The biggest complaint was the constant "men are dumb, they couldn't do this!" attitude that was pushed in your face. However, he said if the exact same movie was made staring the original ghost busters cast, it would actually be good. Assuming you take out the men hating aspects. As far as the script goes, it's a well made ghost busters. He also said that black girl from SNL was actually pretty good in the movie. That horrible line they put in the trailer was funny once you saw the nuance behind it. It's hard to pull a funny moment and put it in a trailer like that.
So that's the review I've heard. Do with it what you want. This clip below is where I heard the review.
