Anime I recommend you watch.

Death Note - Evil Detective show.
Angel Beats - Drama.
Toradora - Drama/Comedy
Gintama - Heavy Comedy with a slice of awesome action.
Tengen Toppa Gurren Lagann - For real men.
La Storia Della Arcana Famiglia - Mafia.
Katekyou Hitman Reborn - Mafia.
Fairy Tail - Wizards and shit.
Spice and Wolf - Merchant, and somewhat romance.
Code:Breaker - A bunch of kids with superpowers kill evil guys.
Psyco Pass - One of my favorites, criminals with futuristic guns hunt down other criminals who are detected by technology. Don't watch it if you have weak nerves.
Zetsuen no Tempest - So there's this chick... she gets killed... and her wanna-be lover wants revenge even if the world gets destroyed... all fuzzy and stuff.
Detective Conan - So there's this kid... and he gets drugged into a brat and then anonymously solves murder cases trying to hunt down the 'Men in Black' who shrank him... also wherever he goes a body appears... it's like a living morgue.
Kuroshitsuji - Please ignore the shit in the name. It's a story about a demon butler who serves a young duke who wants to get revenge for his parents murder. Pretty awesome.

There are a lot more though... and yes... I did watch them all. o.e
