Problem with this Boring Thing
In the first Exorcist film, it's mentioned that it took Merrin a month or more to perform his first exorcism in Africa! Wow, I didn't know a month was actually 10 minutes! People have every right to watch this film with the expectation that it will mostly have to do with someone being possessed and being exorcised, not a religious battle between Native Africans and the British!
Watch Exorcist 3 instead if you want a better sequel - now there's a highly underrated gem!
