Well, i've watched some series and the ones that really impressed me were, Breaking bad, hannibal, boardwalk empire, big bang theory... Has anyone got a suggestion what to watch next?
The British Sherlock, House of Cards, and something old, like the Sopranos might scratch the itch left by Hannibal and Breaking Bad. If you liked BBT you might consider Two and a Half Men. Written and created by the same guy who made Big Bang Theory. Also, "Community". That show has the most laughs-per-minute than any other show I've seen. 30 Rock is that way too. In both these shows there's a good balance of very simple, good humour, and high-brow humour. Finally, a personal favourite that isn't quite related to the shows you watched — The IT Crowd.
I recommend to watch: Dexter http://www.imdb.com/title/tt0773262/ Sons of Anarchy http://www.imdb.com/title/tt1124373/ The Walking Dead http://www.imdb.com/title/tt1520211/ Prison Break http://www.imdb.com/title/tt0455275/ Lost http://www.imdb.com/title/tt0411008/ Misfits http://www.imdb.com/title/tt1548850/ Arrow http://www.imdb.com/title/tt2193021/
The Walking Dead is good for horror and I guess to an extent, some real life situation (if zombie apocalypses do exist). For comedy, I would recommend How I Met Your Mother. Watched all 8 seasons including the 9th season airing right now. Dexter, I haven't caught on yet, but I heard that it's good so I'm going to look into that. A friend of mine did recommend Fringe if you're into science fiction.
I will suggest you to watch Dexters and How I Met Your Mother.Both are awesome one and my favourite too....
