Assuming those of you looking at this set have seen Bela Lugosi in Dracula -- his best movie and in my opionion the best version of Dracula because of it's faithful rendition of Bram Stoker's book which I read at age 15 and coludn't sleep without the light on for a week. Unfortunately, Murders in the Rue Morgue/The Black Cat/The Raven -- all Edgar Allen Poe stories are not followed as faithfully as Dracula, but still worth watching if your a Lugosi fan. The gorilla is not the 'bad guy' in Murder in the Rue Morgue and Lugosi does not portray Instector Dupain the character on which Sherlock Holmes and Poirot are based. The Black Cat is a Satanic battle between good and evil. A good story in itself, but not Poe's. The Raven (forget the later black comedy starring Vincent Price) this is an original horror movie, a little closer to Poe's story while Price's movie is fun, but pure fiction.
The nice thing about being 60 is I've seen these movies either at the theatre or on late night TV as a teen. The Invisible Ray is a B scifi movie, but worth watching if you like that genre. I do. Can't say as I've seen Black Friday so "no comment". This collection is for the Bela Lugosi affectionado and follows the guidelines of the oppressive censorship committee where the evil doctor or mad scientist must always die or be incarcerated. Lugosi, of course, as a true horror hero always chooses death.
Don't expect a rerun of Dracula faithful to the book and you will enjoy this collection. Accept it for what it is a 1934 horror/scifi set and you'll enjoy it immensely. It's important you lay aside your preconceived notions of Poe and watch these flicks as original screenplays starring a great actor and you won't regret buying this series.
