Just getting into this on Netflix. Liking it so far, but am I missing something or are they playing pretty fast and loose with the Vampire mythology? It's a little Stephanie Meyers-esque and it's pissing me off. Mitchell can be out in the daytime? He doesn't seem to need blood at all, and he drinks beer. I've also heard them reference breathing. Does this get explained, or do I just need to go with it and stop being so critical?
