It had some hesitation in the first couple of episodes. I almost found myself disliking the show at first because I agreed more with the main antagonist. I am still a sucker for survivalist type shows that don't require drinking one's own urine. It seems the Rock Lee type character they brought in from the beginning was the only piss we have to drink as he leaves as soon as he appears. I do love Rock Lee, but only in his setting. What would any anime be if it didn't have at least one character that annoys the piss out of you?
So many questions are left after each episode that it brings one to NEED to see what may lay in store next. The semi scientific approach leaves room to spark minds to do more research. If Sheldon from Big Bang grew nuts and then was thrown into the post apocalyptic future, this one be the main character. Character development is a little lacking so far but the series is just getting started. I can't wait to see where we end. I'm staying positive and hoping this remains to be one of the best animes I have seen.
