Eternal tells the tale of the second most well-known vampire, who has his or her origins in real historical people. In this case that person is Countess Elizabeth Báthory, a Hungarian noblewoman who reputedly bathed in the blood of beautiful virgin women in order to keep her youth. And like Dracula in many stories, she has survived to the modern day, hiding in the shadows cast by the world of man.
Unfortunately, just like many other vampire movies, it's not all that great. Mainly because of the poor quality of the script and the actors. Both are obviously doing their best, but it's not enough and the harsh reality that you're watching a movie always shines through. The story also never rises above clichéd murder mystery and the needless change to exotic locations feels more like pandering and following the dotted line than it feels like an actual way to move the story forward.
The biggest problems however is that the story is dull. It has no bite behind it, no soul that would hook you in. And frankly that might have been avoided if they had had the guts to make an honest N-17 film. And I'm not saying that just because I want to see more naked ladies - although I do. But the original story itself is heavy with sexual themes, many many horrible murders and the utter corruption of a mortal woman. To put it another way, look at the cover of the film and tell me that it wouldn't feel more at home in a N-17 movie. That way the film would at least have more crunch to arouse the interest of its audience.
All that being said, I've seen worse vampire films in my lifetime. The actors are not very good, but they're not horrible. The script is lackadaisical, but it's trying. There is some good imagery, the sets are nice and I don't regret seeing it.
