Well, the newest craze I'm going through is Naruto... It's a Japanese animated TV series that comes to the US only though fan-subbing. It's about an obnoxious young ninja-in-training with a demon trapped inside him growing up and learning how to become a real ninja. It's set in the modern world, but with ninjas. It starts off a bit slow and silly, but gets much more exciting and serious with each episode.
For those interested in a good anime that's well worth your download time (though I knocked out my whole apt complex with my downloading), just do a googl search for naruto bittorrent.
Feel free to let me know how crappy a suggestion this is, but be sure to at least watch a couple episodes. The best fansubber seems to be Toriyama's World, but they have only done up to episode 50.
