I really did not like the first anime series. First off I though the animation was not right, and looked kind of bland. The way they exicuted the series with only 26 episodes to use was ok. I really didnt mind the ending except for the whole father dilemma near the end when they go back in time. To tell the truth, I liked the summer and spring OVA's mostly because of the new animation they used on it. Also I thought they were pretty damn funny. I just started watching the new series, and I like it more than the original so far.
