'Jakob's Wife' can't really decide what it wants to be. It goes from a very subtle first act, to an extremely bloody and gory second act, to a comedy third act - almost to the point of becoming slapstick.
This is a very different vampire movie and will be for an acquired taste only. The film's highlight and draw card is undoubtedly screen legend Barbara Crampton, who was excellent as Anne Fedder. I'm not sure whether one could refer to her as the film's protagonist, but she is the lead, and magnificent! She also looks amazing. She plays a woman trapped in a marriage to a minister who repulses her. Once bitten by a vampire - which happened off-screen for some reason, by the way - she undergoes a transformation. This was very exciting, scary and funny. The first act was highly effective with a haunting score.
Unfortunately the film itself transformed, as it turns out. As mentioned, the second act became very bloody; and I mean bucket loads of blood squirting from victims. Unrealistic and overdone, to say the least. It was still entertaining in a way, but it then goes from this gory act to a humorist final act. The creature was scary in the beginning but in the third act he looked like a creature more suited for a comedy - as if a spoof from other vampire movie creations. The humor during the first act was really funny, but it became a bit overbearing during the final act. What a pity.
Still, this is not a bad movie and deserves a watch if you're into this genre - and a MUST if you're a Barbara Crampton fan.
Would I watch it again? I doubt it.
