Complex says: Even though he’s the evilest entity around, Satan apparently has feelings, too. If it’s not exactly sensitivity, then he’s just unwilling to withstand a barrage of elaborate disses, especially from a priest. The exorcist in this underrated sequel takes the name-calling a bit too far, hurling slams like “You author of pain,” and “You corruptor of justice and innocence and youth,” at Beelzebub. The result: Father Button-Pusher gets his skin peeled off while stuck to the ceiling. Unfortunately, he doesn’t use his last breaths to utter any “Yo momma” jokes.
