A sequel and a prequel in the same box!
Traveling back and forth in time and following a dynasty of protagonists who fought Pinhead in one way or another, this movie is a prequel and a sequel at the same time. One third of the plot takes place in space. It features movable sets that it reuses plenty, but in a way to establish a merging of two worlds while saving money. The industrial lighting works well, but it's unusual for Hellraiser.
The storyline is all over the place, as if the movie was filmed in chunks with weak continuity editing and no logical transition. The angled camera gets abusive. The many particle or digital effects look cheap, but the mechanical ones and the prosthetics are some of the best the franchise has known. Pinhead has a lot of spoken lines. Sadly, he loses some of his mystery and dominance, as a result.
Some might find the film confusing; others will miss Clive Barker's sinister style from the two or three first entries. The acting is higher than average, though. The ideas thrown are all interesting; graphically and story-wise, but this one got butchered during editing or relied on it too much. The period piece backstory about the toy box and some cenobites is creative and highly entertaining.
