This was one of the best movies I've ever seen: It's horror, a bit of gruesome scenes mixed with the magic of the reality only Clive Barker can describe in his works.
While watching this movie, pay attention to all the scenes that relate to things previously said, watch the circle close itself.
And enjoy Clive Barker telling you that there is more in the world - more to see, more to feel and more than simply to "be".
