This is a beautifully-done fairy tale in the Old World manner; no pretty princesses and no heroes, just a naughty child, a stern parent, and the inevitable punishment. In this case, the child's unforgivable sin is sucking her thumb. The step-mother calls down the curse of Suckablood, a Nosferatu-like creature who...well, it's pretty obvious. The ending is not.
It's certainly reminiscent of Tim Burton, but not just a knock-off of his style. It has its own voice and texture, and is genuinely creepy. The voice work is very good, with the narrator bringing to mind Boris Karloff without doing an imitation of him. I recommend this to anyone with a love for dark humor and impressive animation/live action hybrids.
