Original Series will always be my favorite since it felt like a complete story with a beginning, middle, and end. Also, it simply has the highest number of episodes I consider my favorites. I enjoy both the important episodes and the one-off stories, and in the first 5 seasons, there's way more hits than misses when it comes to the latter. Also, there's something endearing about how much the show changes over just 5 seasons without losing the traits that made the early episodes good. Probably my least favorite thing about the evolution of the Pokemon Anime after the Original Series was how around Battle Frontier and especially in Diamond and Pearl it started to abandon the sitcom-esque writing that got me hooked on it in the first place.
