I stopped watching the anime around the time of nimbasa. Up until then I had basically marathoned it from the beginning, watching every episode except the special ones, and one about some train in Sinnoh. I just got kind of tired of it I think, as watching all of it in a short timespan makes the anime feel verrrrry repeptitive etc. Also how it took like 200 episodes between gyms in Sinnoh or something. >_> And I think that just made me get tired of it, so I gave up. (Also at that point I had caught up so I had to wait a week between episodes which I wasn't a fan of haha :P)
