Hellraiser: Bloodline (1996)
While the premise is interesting I found the characters and story boring. Some of the gore was really good though like John Merchant being decapitated looked incredible.
Hellraiser: Inferno (2000)
This was a really solid psychological detective noir that I felt brought the franchise back to it's dark, moody and disturbing roots. The designs of the Cenobites were really creepy especially the one without any legs. My only complaint is at times it doesn't really feel like it's part of the Hellraiser franchise and there are not nearly enough Pinhead scenes.
