This TV-series contains 13 episodes of 52 minutes, and all of them are worth to watch. Of course, not all stories are even, there are tops and flops. But all in all, there is no episode that is really bad.
First, the three weakest stories. The fourth episode, "Growing Pains", tells an interesting story about the ghost of a dead boy coming back from the grave to haunt his parents who haven't had enough time to look after him. But too slow paced and a tame ending make this episode rather a letdown. The ninth episode "Carpathian Eagle" boosts a very interesting serial killer story with a twist (and Pierce Brosnan in a small role as a victim), but it's also too slow paced and predictable towards the end. The weakest of all episodes is number ten, "Guardian of the Abyss". It's a not very original story about a Satan's cult, only the final twist is nice to watch.
But there are some exquisite horror stories in the series. For example, episode two, "The Thirteenth Reunion". It's a creepy story about a cannibalistic secret society, highly recommended. As is the sixth episode, "Charlie Boy", the goriest episode with the highest body count about an African voodoo fetish with deadly powers. Or the seventh, "The Silent Scream" starring Peter Cushing as an ex-concentration camp guard who makes a grueling experiment with an ex-convict. Psychologically very unnerving. "Visitor from the Grave", the eleventh episode, has also some creepy moments that are perfectly timed. But the most haunting story is the twelfth, "The Two Faces of Evil", which will make You shiver for quite a while. Atmospheric horror at its best.
The first episode, "Witching Time", starring Ian "Zombi 2" McCullogh, is mainly remarkable for being the only one with a happy-end. "Rude Awakening", the third, is the most (dark) humorous one with Denholm Elliott playing the lead role gleefully funny. The fifth episode "The House That Bled to Death" makes a seven year old girl suffer some really bad shocks, while episode eight, "Children of the Full Moon", tells a nice variation of the classic wolf man story. The final episode, "The Mark of Satan", is an interesting study of a man's paranoia and its unpleasant consequences.
For being a TV-series, the episodes boost surprisingly subversive and violent moments. They are mostly highly entertaining and creepy. Recommended to all who like to shiver while they're watching movies.
