Vampires are cool, and, speaking as one myself, so are autistic people.
We do get lost in our own thoughts often, though, so it’s fitting this character was doing that for a half an hour before suddenly realizing, duh, he’s autistic.
What I didn't like
As I alluded to, I get what Taylor was going for. Still, although getting lost in our own thoughts that fascinate us is the norm for autistics, it would still be nice if there were more of an attempt to make everything leading up to the ending interesting to the audience, too.
