I don’t like Twilight. I don’t like it because it’s the most poorly written book series I’ve read in a long time. I roll my eyes at all the people going nuts about the new movie that just came out. But I’m not going to get into that here. This is a science blog, so I’m going to attack it from a purely scientific standpoint: is this world possible? What biological facts has Stephenie Meyer ignored in order to create her vampires?
