Glad you are enjoying your journeys with the Cenobites. K, to clear up some confusion.
1. The Barker story where he kills Pinhead is called The Scarlet Gospels, which Clive is currently working on, but he says the final draft is going to be 2-3 THOUSAND pages. His publisher wants him to break it up into several books, but he says no.
2. Officially, Barker does not have any creative control over the remake/reboot/reimagining. Weinstein company owns the rights. However, they have done their best to run things past Barker to get his input. The new director, Pascal Laugier, is working very closely with Barker to make this an adaptation of the book The Hellbound Heart. Unlike the first film, Julia is the real villain in the book. The Cenobites are not in it very much, and act more a force of nature, inescapable, rather than either good/evil.
As for the series, here is my rating:
Hellraiser: 5/5
Hellbound: Hellraiser 2 -5/5
Hellraiser 3: Hell on Earth- 3/5
Hellraiser: Bloodlines- 4/5
Hellraiser: Inferno-2/5
Hellraiser: Hellseeker-1/5
Hellraiser: Deader-0.5/5
Hellraiser: Hellworld- .25/5.
The only reason Hellworld got that much point value is due to the ending scene. I thought that was cool. Other than that, it was weaksauce.
Also, Shaun you should watch Nightbreed. Great underrated gem of a movie.
