I went to Skogfjorden when I was 8 .

FURI KURI (FLCL). Man, both anime and manga were incredibly trippy.
Neon Genesis Evangelion. Incredible. Original anime's ending is quite atrophic. I still don't really understand it very well.
Elfin (or Elfen) Lied. The anime is touching, but the original manga is quite whacked, especially near the end.
Pokemon (first seasons only, new stuff is trash). Digimon (limited again to earlier seasons). DBZ was meh-ish. YU-GI-OH.

Looking through manga list...

1/2 (Half) Prince, interesting.
Mahou Sensei Negima! aka: Negima! Magister Negi Mag. lulz
Franken Fran. Awesome.
Record of Fallen Vampire aka: Vampire Juuji Kai. It was interesting in the beginning, but as it progressed, I think it really fell apart. WAY too many "I ACTUALLY HAVE X POWER" reveals.
Happy World. A bit strange, but certainly worth reading until the end, IMO.
Air. I don't really get it. It extracted a "meh" reaction from me.
Tsuiteru Kanojo. Quite sweet/funny/lulzy, actually.

Aaaand that's it from me so far. lolis

DBZ was badass, but it got annoying when they introduced:
"zomg, Goku died again. He must like martyrdom. Oh, [insert name resembling other stuffs here] is coming to kill all human/namekian/universal life, gotta get those damn balls again."
Also, about the same time, this happened:
"I (Goku) am getting beat. Time for some deus ex machina to come along and let me save others, and probably die. OH YOU BAD MAN YOU KILLED KRILLIN!"

That's what I love about it They made a movie with an alternate ending later (The End of Evangelion) and I assume there will be yet another different ending in the final Evangelion movie remake when it comes.
