Quoted from keys88:The walking dead is the best out there. But you must watch from the start.
I got to season three of Walking Dead and it started to get old for me. Storyline or no storyline I got tired of them running or chasing after zombies.
GOT is a fantastic series if you have not seen it yet. Many other networks have tried to duplicate the magic of GOT with little success. Great story line and characters.
I also really enjoyed 24 series (helps with appreciating the game)
Currently watching CSI series and enjoying them.
Also Lost is a must if you have never seen it.
