I loved the first two or three seasons, but once they got into the future arc, I lost interest. I felt like it lost a lot of its charm after that point. I still watched a bit of the future arc, but it didn't hold the same magic for me that say, the Varia Unit arc did. Still, it was incredibly well done for an anime based almost strictly off the manga. And when I mean strictly, I mean STRICTLY. The joke about KHR is that it was originally only supposed to be a gag manga and the artist decided to turn it into a battle manga, though I don't really know why!
