Since I dislike anime.. can I have a Top 3 list only?
1. Excel Saga
Old school anime <3 I hate people who don't "get it" because it relies so much on references to other shows and cartoons... it's a great series with a lot of humor, especially the LAST episode "Too Far". I still own the DVD's
2. The Melancholy of Haruhi Suzumiya
I love both the novels and the anime. It has the most amazing animation I've seen since... FLCL. Truth to the gods. It was also a very clever analogical build-up to climax the series after the first few episodes, making them the last
3. FLCL
As mentioned above, great animation. I like the manga more for the action sequences, but, the message can still get through to everyone: PENISES. Seriously. It's ALL about the penises <3 XD
