Another Hunter x Hunter post (hey, it's a long series): the show is fairly self-aware. For example, I noticed that the protagonist, Gon, is not really a "good guy" like the protagonists of a lot of shonen. Sure enough, in the very next episode, they discuss this in-show (as a thought Killua has). I've noticed things that seem like plot holes which usually get addressed on-screen shortly thereafter. I also like how the author gives sympathetic qualities to a lot of the villains. Not all, but he definitely seems to have sociopaths, and villains with a motivation.
