“Blood Ransom” is a slow burn crime thriller that fearlessly takes on the whole vampire genre. As if oblivious to “Twilight,” this vampire love story is a noir-tinged offbeat adventure harking back to the ’70s. It’s got your basic adreniline-fuled plot, vampire gang vs. the one guy who might make a difference, plus a bunch of quirky twists. And much of what makes this work is a strong cast, starring Alexander Dreymon, as the lone wolf hero, in love with Anne Curtis, as the mysterious vampire vixen.
