Ping Pong the animation gave me mixed signals in the first episode. I toughed it out through episode three and the show became great very quickly. The story in itself is amazing, but very basic: it's about conflict with one's self and this theme can be seen in EVERY character. The art is very very different, but after episode three you find it funny and enjoyable. Like I already said, the story is amazing, and you can't have an amazing story without amazing characters. Once the final credits roll, you kind of wish there was another season (or 20 episodes). I enjoyed this very much and would recommend it to anyone.
Enjoy.
