I don't quite understand the point...
The animation and voice acting are good, but I just don't think many people would ever wish to be the last man on earth. Surely people get fed up with their family and wish to be away from them, but that's a different story. I guess what I'm saying is I'm not sure who this is targeted at. Maybe more people than I think, hence the high rating, but it just didn't do it for me. Keep animating though, I dig the art style!
