La strage dei vampiri

I first watched this film on TV in the late 60's, early 70's. At that time i thought that it was a pretty good film. Recently, i purchased it on DVD and have, somewhat, changed my mind. The atmosphere, castle and surrounding settings are very good, however, the acting could be better. The opening sequence is great, however, the movie goes downhill from there. Graziella Granata, is drop dead gorgeous and Walter Brandi, her husband/male lead is OK. My main problem is with Dieter Eppler, the Vampire. He is way too stiff and his makeup is overdone. He,i assume, does his best with what he has to work with but looks like an extra in a stage play, who just comes in and out. The music is fine and the film, overall, is worth watching. I just feel that it could have been so much better. John R. Tracy
