TL;DR – If you have never seen a Ghostbusters film then you should really enjoy this, if you have, it will take a bit to get use to the cast, but by the end you will be all on board.
Score – 3 out of 5 stars
P.S. there is a post-credits scene
Ghostbusters as a movie is really quite simple, you have a bunch of people that stop Ghosts. The title of the film pretty much tells you everything you need to know about the story before you go to see it.
