The overarching problem with Ghostbusters is that the script is a greater abomination to God than any of the demons and ghosts in the franchise. I’m sure they could have done a worse job, but they’d have to study Tobin’s Spirit Guide to summon a script from an even deeper circle of Hell.
Mostly, it’s a lack of intelligence. In the original movie, the bad guys weren’t actually the ghosts — everybody loves Slimer and the Marshmallow Man. No, the bad guys were the clueless bureaucrats in the government, who set off a supernatural crisis through bumbling and red tape.
In this film, by contrast, the enemy is all men, while the government ends up playing dad. Every man in the movie is a combination of malevolent and moronic. The chick ‘busters shame the mayor so much they end up getting government funding at the end. Like all feminists, they can only survive by sucking on the teat of Big Government.
