Digimon 02 is "let's throw shit to a wall and see what sticks" The best villain was Demon, who appeared for a grand total of one episode. And they completely ignore the Cthulhu thing, too.
Doesn't help that the only good characters are Ken, TK and Kari somewhat. Davis is Tai with none of the good and I swear they wanted to make Yolei and Cody unlikable. And what's up with the whole "not killing" bullshit?
At least the music was cool. And most Digimon.
Yeah the dark world thing or whatever it was was supposed to be a full blown story arc but it was cut for some reason. I'm fairly certain it was written by the same guy who did Tamers which explains why it was so dark compared to the rest of S2.
But yeah Ken, TK, and Kari are the only ones I actually like. Davis is annoying as hell the first half but becomes better once he and Ken become friends. And Cody and Yolei are just fucking annoying the whole time.
