Base Breaker: The Protagonist, Detective Joseph Thorne. He's a manipulative Jerkass of the highest order, who steals evidence, cheats on his wife, frames his partner, and robs dead people. On the one hand he's a Villain Protagonist rather than a Designated Hero who's terrible actions are framed as shitty, and in the end he's a very deserved Asshole Victim. On the other hand, following such a loathsome asshole can make the movie tedious and repellent.
Surprisingly Improved Sequel: After two movies where Pinhead suffered Villain Decay and an overuse of splatter horror while losing the creepy atmosphere, the fifth movie in the series returns Pinhead to his roots and tones down the gore a lot by moving to mainly psychological horror.
