Inferno & Deader are two underrated Masterpieces.
I've always thought that Inferno(Hellraiser 5) & Deader(Hellraiser 7) are some purely and simply underrated Masterpieces from the franchise.
I like Hellraiser,Hellhound:Hellraiser II,Hellraiser III:Hell on Earth, & Hellraiser:Hellseeker but out of the bunch 5 & 7 truly standout as the most unique and special of the bunch.
I dislike Hellworld & Revelations.
Inferno is just a cool neo noir cop film that uses Pinhead as a moral figure.
Deader deals with a foreign location and some neat Cult sub-plot.
