I thought the trailer looked bad. While there was a couple moments I liked most of it looked like a bad remake that just insults the original with annoying campy comedy. It felt like they based this remake after the cartoon and not the movies.
I was more hoping for a Ghostbusters "the Next Generation" where one (or two) of the women is related to Egon and/or Ray and restarts the business. I saw NOTHING that made the original a classic. But maybe the trailer was just badly put together the the movie will surprise me.
