Other reviewers (at least the ones I read) must have watched a different movie to me. What I saw was certainly an effort at originality, and yes, it was better than some of the other sequels to the franchise, but that said it was still a below par screenplay, borrowing heavily from other, cleverer, more original films.
Ironically Hellraiser:Hellseeker shares some of the same flawed plot concepts as the movie it borrows most heavily from: Jacob's Ladder. There's the same two tier story running consecutively and along different, mysterious time-lines, both of which fail utterly to fuse into a single coherent time-line at the end of the film. There's the same solipsist nightmare: how can one truly discern between reality and dreams when the dream state feels as 'real' as reality itself? The second movie from which Hellseeker shamelessly borrows is Angel Heart, a masterpiece of cinematic horror featuring Mickey Rourke before his face went to hell (as a result of high living, screwed up plastic surgery and boxing, not Pinhead) and Robert DeNiro. Where Angel Heart is innovative, Hellseeker is simply repetitive and boring. Where Mickey Rourke excels as the confused protagonist in Angel Heart, Dean Winters sleep-walks his way through the role in Hellseeker, and where DeNiro gets all the best lines, poor Pinhead gets some of the most forgettable I've ever heard him utter.
Granted, compared with the other Hellraiser sequels (all bar Hell on Earth, which I have to say I enjoyed more than I or II) this tries something different, and maybe with a better lead role there'd be something there worthy of a couple more stars. But ultimately the confused mess of a plot destroys itself, irrespective of Winters' deadpan portrayal.
I give this rubbish one star for effort and one for the inclusion of Ashley Laurence who, lets face it, should really be above all this by now. Another star for Doug Bradley as Pinhead who never fails to send chills down my spine with his black 8-ball eyes and his tendency to drag nine inch nails out of his own skull.
Ultimately though, Doug needs to share that last star with Clive Barker without whom the world would be a much duller place.
