Finally saw it as well. It just didn't really do anything for me. I appreciated they didn't do a rehash of Gozer and tried a new villain. But it was so flat. None of the characters had any real dimension except for McCarthy's character. Wiig was just annoying. McKinnon was funny but her entire character was just a one note schtick. Jones turned out better than the marketing had us believe, but I didn't get how one minute she wants to be a Ghostbuster and the next minute she's acting like the job was forced on her.
The cameos were awful, especially Murray's. And I'm not sure how the proton packs work. They just swing the ghosts around and destroy them? No need to trap them anymore?
And this is just because I live in NY, but it was obvious they didn't really film a lot of it here. In the original, the city felt as much a character in the movie as anyone else. I didn't get that feeling here as it was obvious it was shot somewhere else.
