I'm a fan. I'm also a long time fan of the originals as well.
You can tell they added certain things in response to the hate the mere idea of the movie garnered as soon as it was announced, which didn't endear them to certain subsets of fans. But overall it was a fun movie, and I think they did a good job. I also like how they're connecting the two different Ghostbusters worlds in the idw comics. I do hope they make a second movie, or Ivan Reitman is given a chance to make his movie that bridges the two universes that he has recently talked about wanting to do.
