This movie is oddly sexist and anti male
I mean it.
Every guy in the movie is either a complete dolt or completely against the girls. The professor is a cranky old man who fires her. Chris Hemsworth plays a hot idiot. The main bad guy is a doofus who breaks out into dance. They beat the main ghost by shooting it in the balls. There's that doofus who poops his pants in the beginning etc.
Imagine the reverse: a team of guys are so smart but the stupid women keep holding them down. The professors and academia are a bunch of stupid girls. Then the guys get this hot stupid secretary. Then they defeat the main female ghost by shooting her in the chest. A girl gets scared by a ghost and poops her pants. And all the while women in the movie continue to be stupid and fuck up.
This definitely would never be made. That's why this film is so odd. It's so blatantly anti men. No male character in this movie is smart or a good role model. Just a doopy loser or a jackass.
