You know you're in trouble when a once reputable horror franchinse throws a "katching" sound effect and Pinhead's likeness at you before the opening title. The plot, dealing with the bloodline of a toy maker(?) that created the evil puzzle box, is cheap, boring, and contrived. The little gore is unnecessary (such as the autopsy of a body for no apparent reason), and the now cut-rate CGI box looks incredibly lame. Also, the conclusion - where a space station folds into a giant puzzle box - is a disgrace. The worst in the series.
The bottom line: Even fans of this will be disappointed. You may just want to skip ahead to Hellraiser: Inferno, as it�s a pretty decent little thriller. Love the twin brother security guards. Though, I'm not sure of their relevance to the story.
