I did at the end of DP. I think the story-line of pokemon is going basically no where. The characters aren't aging, continuous character replacements doesn't help the cause either. Has became too predictive and repetitive.
Yet, your username and avatar is Shooti.. Real credibility there mate.
And predictive?
Myself, I tried to watch Johto in its entirety when it first came out, but the Dutch network didn't air it all in one go, so it became tough to watch them all in the correct order, but eventually, with reruns, I managed to watch them all. Then came highschool and conflicting scheduals, so I basically missed a lot of AG due to that, also, saturday mornings weren't my thing in highschool.. Sports got in the way as well, not to mention that the airing of AG basically stopped somewhere around Dewford/Mauville and kept on rerunning in my experience since then. Then I went to the States, and barely watched any episodes at all, though I started to view episode pictures on Serebii for some of the last episodes of Battle Frontier. Hence my total lack of licking May/Max/Drew/Harley, because they were introduced in a time which I didn't watch pokemon.
Continuing, I watched most of the first few DP episodes in picture form, and then started to watch streams around the time of the tagbattle arc. Since then, I only miss a few episodes..
