I watched Twins of Evil recently, too! And, yeah. I knew nothing about it going in, except it came before Lust For a Vampire, so I can't say I had any sort of expectation, but it wasn't bad, if a bit obviously trying too hard with the twins. Some really nice visuals and a particularly terrible incarnation of Peter Cushing, and Damien Thomas had a super-dramatic moment at the end that made me giggle. (I don't measure horror films by how much they make me laugh... *coughs* Lust for a Vampire was a winner on that front; I could not delete it after. It was v iddy and amusing and the heroine actually almost did stuff, amazing. Also now I understand what Michael Johnston had done to deserve the worst wig ever in Shadow of the Tower.)

(Talking Pictures seem to be gradually showing the Karnstein trilogy, but backwards, idk?)
