This was a tough one. The original is in my top ten of all time, maybe top 5, so it's hard to be objective. First off, the cast is EXCELLENT. Great casting. Each of the leads brings something unique to their role equating to the sum being greater than its parts. McKinnon in particular just gets more and more interesting as the film goes on. She may be my favorite of the team (okay, no, that would be Wiig because she's always amazing). There's great chemistry and I am excited to see all of them in future installments.
Including Chris Hemsworth. Because Hemsworth STEALS THE GODDAMN MOVIE. He is the single funniest part of the movie. It's almost worth seeing it for his performance alone.
So yeah. GREAT cast.
The plot sucks. Or not even the plot, just kind of the overall pacing and structure. The core plot about some internet pimpleboy gamergater lookin dude with delusions of otherworldy grandeur is a giant middle finger to the same detractors who frothed at the mouth at the idea of an all woman Ghostbusters. So kudos to that storyline. It's just that the film kind of meanders to get there. Again, this is where the original is pure genius so hard to be fair in that regard.
I would call it a rental, but also a fun summer flick if you have the time.
