Query: Very uneven

I wanted to like this series but I found it very schizophrenic. It tries to be very dark with gallons of blood spilled by even the slightest wound, but then abruptly charges gears (and art styles) into juvenile cutesy-poo humor. Add to the fact you only get four episodes in a huge box set makes this a very poor value.
