Everyone go catch some Pokémon!!!!
The Pokémon Anime is great. I pretty much like all of the main characters.
I've seen most of the Indigo League, save for a few episodes. I've seen every episode in the Orange League, I believe. I've seen most of the Johto episodes, except for the last 15-20 episodes. I've seen some of the Advanced Generation episodes, the early to middle portion of AG Hoenn. Lastly, I've seen some of the early Diamond and Pearl episodes, as well as some the later ones (75s to 90s).
