the reason be represent 1. a very embarrassing greece dance 2. there be more many woman than men in the film except the underrated actor ralph bates and the unknown actor michael johnson 3. the pretty blond danish model jutte steensgard be not a famous horror actress . she play carmilla karnstein a bit boring and the reason be that she be not really an actress but she be a model . if the famous horror actress barbara steele would play in that role and the movie would have be very different . 4. the same plot 19th century romanticism ( a classic gothic horror tale ) and which hammer film studio do not develop the story at all . the most stupid element in the movie represent a young writer who fell in love in a female vampire and and could not save her and be unable to protect himself . it look a bit cheesy and cause you would already see this in various hammer film . 2 3 star a a result .
