Hunter X Hunter: I'd heard several recommendations that this was some kind of "thinking man's shonen", which it hasn't really lived up to so far (I'm around episode 80, so I understand I've finished all the complete arcs and are about to start the ongoing one). The powers seem very arbitrary (far more so than e.g. Fate/*), and any number of characters seem to be massively overpowered if they'd think a little more about how they use their abilities. It's hard to get a coherent sense of the world, because there are a huge number of differences from reality that one would expect to radically change the world, but the consequences of these things aren't really explored or visible, so it never felt real to me.

I'll keep watching - the way the various plot threads interact is quite clever, and some of the powers and fights are quite fun, but I can't really recommend this.
