I really wish it had been funnier, considering the various comic talents involved. There were (for me) cringe-y bits and silly one-liners that could have been written better, but the parts that were laugh-out-loud funny made up for them.
The Hubs mentioned afterward as we were walking home how the new Ghostbusters are not straight-up female versions of the original cast. Like, you can't take one of them and say, "Oh, she's the Venkman of the group, and that other gal is the Ray..." and such. They are all new, with totally different personalities that set them apart from the characters we all know and love from the original films.
The one big takeaway from the movie: Holtzman. She is my new spirit animal.
