Samuel is telling the story of a female vampire he once fell in love with a long time ago, followed by his meeting with a woman much like her in present day.
"Historia Muerta" is a short film mostly driven by its narration. The visuals just serve as an attempt to bring the words to life. The narrator, Samuel, is speaking of a woman he met many years ago (hundreds of years ago) - the woman he fell in love with, who was also a vampire. He met her, got love struck and then he didn't see her again. Until now.
I don't want to go into details, but it's an interesting way of mixing the classic, gothic vampire story with a more modern approach. It fits all the criteria to work as both, too. Still, I did not find myself engaged by this short film. Its narration is already covering all bases, that the visuals seems pointless. In my opinion, "Historia Muerta" should've been a short story (or even a poem), not a film. The visuals aren't bad, but they have nothing to say that the narration isn't covering already. You simply don't need the visuals, and what kind of film does that make it?
Still, I need to judge the visuals and be fair: if seen as a moving poem, maybe then it works? Possibly. It's not purely negative that that the narration is in focus, since it shows how they've managed to fit the visuals really well. Some parts are quite well made, some are not (pretty cheesy at times), but at the end of the day I can't say that the visual part of the film entertained enough.
Period pieces are hard to swallow on a small budget and gothic vampires are a risk as they're often very bland. "Historia Muerta" have some powerful enemies to fight, and for me the battle didn't end well for the short film. As a short story or poem I think it's good, but I did not see much use of the visuals. It might not seem like a big deal but I reckon that it is, as I came to watch and listen, not just the latter. Still a great show reel for the filmmakers, though.
