In all honesty, I'm not really feeling too crazy for either Parasyte or Akame Ga Kill, which is kind of weird considering that a lot of my favorite anime are usually spilling with blood and violence, at least the anime versions. At least in the latter's case, they aren't afraid of killing the main cast off, so there's some incentive to which member of Night Raid gets whacked next, along with the next bad guy as well. In both cases though, you're better off reading the manga.
One thing that does annoy me about AGK is that there is often such a sudden shift in tone every few moments, it's literately bone-jarring. I understand wanting to lighten up the mood to keep it from taking itself too seriously, but there are much better ways of putting in humor in a dark series like AGK. In fairness, after watching/reading Berserk and Hellsing Ultimate {both are over the top in carnage and grimdarkness, but Berserk plays it seriously while Hellsing relishes in cartoon-y absurdity of it all} it's kind of hard to take any anime that seems to follow in its footsteps seriously ever again, and that's not including the works of Go Nagai, but maybe that's just me speaking.
