In the Shadow of the Moon

A vampire reappears every 9 years to kill people, she also seems able to travel through time.
Of course, nobody believes the cop in charge of the investigation. As a result, he gradually loses his mind trying to figure out the mystery.

Unfortunately, everything is revealed during a never-ending dialogue that put me to sleep. I still don’t know why the time-traveller vampire was killing all these people and I will probably never know because I’ve lost all interest. It wasn’t badly acted though, but that’s about all I can say about the movie.
