Most of these were prolly already mentioned if not all of them but this thread is way too long for me to go through the whole thing but.....

Must Watch IMO

Trigun
Cowboy Bebop
FLCL (only six episodes but still very good)
Death Note

I would say bleach too, but im fairly certain its a very high rated show and many anime fans have already seen it

as for the aforementioned ive never looked and could very well be high rated themselves idk, i guess im just ranting now, but if you havent seen them check 'em out
