It's starts well enough and the first half of the movie makes you think this is another modern day Irish classic horror. But and it is a big but - the whole thing runs out of steam (or script perhaps) and most of the second half is taken up with an overpadded, overblown and (as it wears on and grates) unterrifying finale.
The concept of this film is terrifying and it has a little more meat on the bones than other films of this era. It's a twisted romance in a great setting and the horror is more implied than visual. As a very loose sequel to White Zombie it is just about worth the effort.
Let's face it anything with Olivier is fantastic, even if this is a little low brow by his standards. Steeped in fantasy but the setting and characters are real. Thoroughly entertaining it could almost be one of The Omen films in terms of its style and atmosphere.
