As far as b-grade horror films go, these are excellent films, as one might expect from the famous Hammer studios. Several of the films have a young, gorgeous Oliver Reed, as well as Peter Cushing and the improbably beautiful Yvonne Romain.
I'll explain the films in brief: Brides of Dracula is the usual Hammer material the passes on cable, viz. a young lady is the target of a follower of Dracula and Peter Cushing comes to the rescue.
Curse of the Werewolf I found to be a surprisingly original film. Oliver Reed is the werewolf, but you only see him about thirty minutes into the film. We start with the story of his conception instead, a sort of history of cruelty to culminates in werewolf's violence.
Paranoiac and Nightmare are psychological thrillers that are very engrossing, much superior to modern horror. However, don't expect much intellectual content, despite the intelligent scripts.
Night Creatures is about soldiers seeking a notorious pirate. There are some interesting characters in this film that make it interesting.
The other two are fairly self-explanatory. In short, the films in this set are much better than average b-grade horror films, intelligently written and directed in an inobtrusive style, and very well-acted by Cushing, Reed, et al.; but these are, of course, not cinematic masterpieces.
As for the DVDs themselves, there are no special features, just the lovely box they come in. I found the picture and sound to be excellent. However, I have found the DVDs in this set to sometimes skip and freeze on my overly-sensitive DVD player.
