Well yes, this is the point where I say “Yes, I have, I’ve seen *** and *** and *** and a dozen more because friends of mine wank all over that shit and keep telling me to watch it”, and you’ll reply with “See, those are the shitty ones, watch some proper ones!”.
But for your amusement, I’ll give you a list (forgive me if I spelled most of them wrong)
Elfen Leid, Death Note, Hellsing, Full Metal Alchemist, Some Gundam stuff, Dragonball (Z, GT), Samurai Champloo, Rurouni Kenshin, Vampire Hunter, Cowboy Bebop, Bleach, and probably a bunch more.
Everything I saw was utter shite in terms of visuals and storytelling. Don’t trust the Japanese with telling proper stories. Ever.
