*Tried* being the key part. I gave up around 2/3rds of the way in, much to
ernads annoyance(she was hoping to have another series we can watch together). At least this time I can articulate the reasons:
1) You have families that have been fighting these creatures for what, 200 years? At least? And they still haven't learned that the best way to make sure the line survives is teach their children everything they can at an early age? Rather, they still think that the best way to survive is hide everything from the children and hope like hell they aren't the ones chosen? I really really hate that trope.
2) No built in support structure that I can see. Are these guys for real?That's worse then Buffy. At least Slayers had support infrastructure, including some built-in intelligence capability, and someone who was supposed to teach them, even if the actual set-up was abominable.
3)Who the fuck, when he has a cooperative knowledgeable local doesn't stop for a couple of minutes and pump the guy for as much immediately relevant intel as he can get? And then starts debating with that local what they should do?
tl;dr - the show premises sets the protagonist and his whole line as incompetent. I don't really like these kind of shows.
