I can't rave about it enough. It was smooth, very well plotted, a nicely twisting story, and never fell into the "big effects, big action" trap. Where an American series would have tried to keep you riveted with it's huge car chases, gun battles, and explosions, this chose to involve you in a plot that kept your mind working until the final scene. What effects did exist were sparse, making each one worth seeing, and never for flash but within the story's framework. Conspiracy, betrayal, confusion, drama, action, suspense...wow. As a final, game-winning stroke, this is a story involving vampires, and yet, they rarely show up on screen, and when they do, there's no fangs, no grey flesh, no turning-into-animals, no turning-into-smoke, no supernatural whatsis. Other than their rather explosive form of death and one really cool moment at the end, they're nearly indistinguishable from human.
It was amazing, it was stylish, it was deep...which means it's no wonder Mr. and Mrs. America will never appreciate it. Too bad, really. I highly, highly recommend it to those who want and expect more from their entertainment.
