Forget the F-Bomb here's the A-Bomb
When her father remarries Nancy (Sandra Harrison) finds herself packed off to a boarding school when she doesn't get on with her new stepmum. She also doesn't get on with her fellow students who punk her as soon as she arrives. But Nancy comes to the attention of Miss Branding (Louise Lewis) the chemistry teacher who believes she can transform people through hypnosis, a theory which is ignored by other male scientists. And that is what Miss Branding does by bringing out the vampire in Nancy she uses her to commit a series of murders, completely oblivious to her actions when she wakes up. That is all well and good but what happens when Miss Branding can't control Nancy.
Filed under interesting, that is what I place "Blood Is My Heritage", aka "Blood of Dracula", under as it isn't really entertaining and not really a bad movie either but not something which you need to see more than once. I say filed under interesting because this was one of those AIP teen horror movies of the 50s with "I Was a Teenage Werewolf" being the most famous of these movies. There is nothing amazing about these movies with many of them built to a formula which is now quite cheesy with scenes depicting what teens got up to from dancing with cushions in dorms or having a sing along with a singer who shows up, in this case we get a rendition of "Puppy Love".
The trouble is that not only does it make "Blood is my Heritage" cheesily dated it doesn't really have the horror to make it memorable. In fact after a surprising amount of nothing with scenes of teens being teens we get the horror which is less about Miss Branding and bringing the vampire out in Nancy but what happens when Miss Branding loses control of Nancy's dark side.
What this all boils down to is that "Blood is my Heritage" is entertaining in a kind of dated/cheesy way and it is interesting as a look at teen horror movies of the 50s. But beyond an almost historic/curious appeal it doesn't offer much else.
