Finally saw Ghostbusters. It was enjoyable, but it's not great. It's definitely worth watching at least once. I wouldn't bother with 3D, as it did nothing for me. A couple of scenes work for it, especially projectile vomiting.
Overall, it was a pretty good story with competently played characters. The humor factor is not as high as I'd had hoped. I got some laughs out of it, but I wouldn't call it rip-roaring. I felt the best character was Holtzmann with her mad scientist vibe. Sadly, she was also the weakest in terms of story; we know nothing about her. The relationship between Erin and Abby was pretty solid. Patty brought in her street smarts, because every group of nerds needs someone with street smarts. The receptionist, Kevin, was a caricature of idiocy and vapidness. The over-the-top stupidity of the character rivaled Chris Pratt in Parks and Rec but without the charm.
I felt the opening scene was a little disjointed. It presented an air of malice and danger with a murderous spirit that didn't really mesh with the overall light-hearted feeling of the movie. The fight in Times Square also felt odd to me since the proton packs were used in ways I wasn't anticipating, but if you view it without any comparison to the original movie, then why not use the proton packs that way? Also, our mad scientist invents other devices for incapacitating ghosts. Those scenes were the only ones that really stood out as subpar to me, and honestly the Times Square scene was short enough that it was not unwelcome. When you compare it to really tedious fight scenes like the Matrix or Snowpiercer, this is really nothing.
There are plenty of homages to the original. The fire station makes an appearance. Each principal living actor from the original minus Moranis made an appearance (I guess Peck wasn't principal enough or that actor declined to appear). Seeing them each was a cute little zinger as you recognize the actor--which does detract a bit. As much as I wanted to enjoy each one, I really didn't like Aykroyd's cameo. The others were pretty good. And yes, you'll see the Stay-Puft Marshmallow Man and Slimer. The movie is very cognizant of its fanboys and fangirls, and it pays us plenty of lip service.
The villain was the weakest link, I felt. We could have learned more about him. His plot was straightforward enough, and we could gather his motivation, but he was really just a one-dimensional plot device. Deleted scenes of his background may make this a stronger part of the movie.
So I suppose I'd probably give it a 7 or 8 out of 10. I'm leaning toward 8, but I tend to nitpick movies a bit after watching them. Whether it does get downgraded to a 7 will depend on how it stands up to that post-viewing nitpicking.
