I absolutely loved it! The effects were amazing, thought there were so many it wasn't overwhelming. I like how they didn't go with the 'vampire burns in the light' shtick. I also love how he truly had the abilities to hone into his sense like a bat would, it felt like it made far more sense than any other vampire based things there are out there. I also loved (spoilers if you haven't seen it)
That as the doctor he was far more sensible on what was happening, he wanted to be more ethical. He wasn't a Villian, just an antihero. I also liked how the villian wasn't exactly doing it just to be mean or anything, he was doing it to force the doctor to EMBRACE it. It felt more like a genuine sense of power hungry relationship. If I could give this a six or above I would. I wish to rewatch it over and over and over.
