What do you think of anitwitter's comparisons of Tokyo Ghoul and Parasyte? It seems a lot of people think that Tokyo Ghoul did what Parasyte is trying to do but better as far as body horror/alienation (heh) drama go. A better first question would be "Did you watch Tokyo Ghoul?"
I watched the first 2-3 episodes and lost interest, so I guess that's where I stand on Tokyo Ghoul versus Parasyte.
