Clive Barker wrote this back in the 80s I believe and there it sat in the minds of his readers. I confess I have not read the story but I have read other works by Clive and I have to say this film was very well thought up thanks to the director , writer collaboration.
The reviews above slam it for being lacklustre. But you have to remember Barker is not about quick gore payoffs, obvious chase scenes.
His work is all about character build ups and dark personalities forcing their way out during times of dytopic suburban nightmares.
The pacing was what I expected, slow, creepy and intense. Not too slow in my opinion but others may find it so. Depends what you want from horror. I loved Silent Hill as well for it's surreal nightmare and intense choking threat.
The train forever leading down, down into a chasm of the inexplicable mind that is Barker. I thought Vinnie played the silent nightmare well despite being recognisable. Look at his face, you can't get a more beaten up (rugby player) look from an actor playing a monster. Boris Karloff anyone.
I recomend this film for it's superb photographic direction as well as creepy vibe overall.
The story itself needs a little more clue in but other parts leave an educated audience to discover the nightmare for themselves.
