My 3 cents on Digimon:
I love Digimon Adventure/02. They were both pretty good, and somehow they managed to fulfill character development (Something Pokemon doesn't do very well). Am I the only one who loved 02 even after Ken turned native? I mean a few episodes later we get BlackWarGreymon, who is pretty much my favorite emo anime charcter ever.

Digimon Tamers is indisputably the best monster battle anime around. It had your run of the mill "normal kid's dreams come true" story that became so much more. As it's already been said the series was really dark, but kept the childhood dream feeling of the show in place. Plus, I love that the Digimon's origin story is the evolution of a program developed in the 70's (Right, 70's?).

Digimon Frontier wasn't that great. I watched all of Frontier and the opinions that came out of it from me are: twin brother plot twist was great, villains were great, characters were lame, I hated the Hybrid Evolution thing at first, but it grew on me, and the plot was boring. It didn't help that I had to watch that series at 5:00 in the morning.

I made it halfway through Digimon Savers/Data Squad and didn't think it was worth finishing. Also, what's up with people and the villain's "motive" in this series. What, he was racist against Digimon, that was about it, lame. I liked the fact that the lead character's dad worked for an exploration force to the Digital World, that the main character punched the opposing Digimon, and I'm sure that there's some little stuff too. The series's characters didn't do it for me and what was up with all the Digi-evolution's being weird and taken out of the video games or something?
