One time I was so into it, I went ahead and watched the subbed episodes online, all the way up to the latest one airing in Japan. Then it became one of my weekly anime seasonal watches until its end in 2012.
No matter how bad, I was very devoted to not missing an episode. The filler arc with Nozomi and Kon was pretty much the only one I skipped, because I was so upset that it was yet another long filler arc after JUST HAVING one before it!
