My impression: I really enjoyed it. I'm very glad that the movie was not an adaptation of the earlier films. It just took the idea of a group of scientific friends who believe in ghosts who wound up chasing ghosts and saving New York City and ran with it. I really appreciated that. A buddy movie should be a buddy movie whether it is an all male or female cast. Comedy is comedy no matter who you are. (There was a bit of a thrill at watching Chris Hemsworth in the role of a male blonde bimbo). His comedic timing was quite impressive and makes me hope that someone will take another leap and cast him in another comedic role where he can have a bit more fun.
Although I have heard criticism that some of the performances were over the top, and that the movie missed the chance to make a statement for Feminism, I think that is a bit much for a summer film.. Was it fun? yes. Did I laugh? Yes. Did I jump? YEs. Did it remind me why I liked the first ones? YES. Did it make me want to be a Ghostbuster? Heck, YEAH! Those gadgets were just toooo AWESOME!!!
