Everyone needs to get on and help Josh learn about the good stuff anime has to offer. OK so I will give you a list of my fav classic and must see shows. Obviously my favs probably won't always fall in line with your likes, but it's a start.
DBZ is kind of a given if your a guy or really anyone who's ever seen anime ever
Durarara is a newer show on Crunchyroll.com that is easy to get a hold of and short
Ranma ½ I won't explain you just have to watch it
Vampire Hunter D amaaaaazing!
Cowboy Bebop ok so for a brief two years the Japanese tried to make anime that would appeal to American audiences and it worked.
Akira classic but again unexplainable
Metropolis Osamu Tezuka the creator of modern anime at his best
Any Miyazaki film you really honestly can't go wrong but I really like Princess Mononoke, My Neighbor Totoro, Kiki's Delivery Service or Spirited Away
Slayers umm it's like screwy D&D madness with a really short sorceress
Honestly this is only the beginning and I'm sure Nate will have more to add. MY favorite is Sailor Moon, but it's really girly so you probably wouldn't like it.
