Hellraiser 7: Deader. This was the european death cult one. This one was also actuallynot so bad. If you found it while scrounging for cheapo horror on Netflix, you'd think you found a treasure. It is a little repetitive, and it does suffer from the "features 5 minutes of Pinhead" issue, but hey, it ain't bad.
Hellraiser 6: Hellseeker was really bad, though. Like 5, it feels like a noir-y Tales from the Crypt episode with Pinhead stapled in, but it's not nearly as well done, which is saying something because 5 was not well done. The music is notably bad. Kristy from the first two movies is in it. Warning: it bad.
Moving on to Hellworld, the MMO one. I remember this one being delightfully bad in a fun way.
