Top tv series...IMHO
1. supernatural - supposed to be scary, but it's more of an action type thriller. Two brothers go round in a 67' chevy impala hard top and kill creepy crawly things. Like ghosts, shapeshifters, vampires, demons and what not. It's like if Van Helsing had a brother.
2. The Walking Dead - you've already watched it.
3. Wilfred - the dude that plays frodo sees a dog like its a person in a dog suit and can talk to/understand the dog, the show is hilarious and not anything like as boring as I just made it sound.
4. Monk - if you're craving detective mysteries nothin is better, beats the repetitiveness of the NCIS. It's awesome think like a modern Sherlock Holmes that only notices things because he is OCD and has thousands of phobias.
5. House - Just started watching it on TV and I must say it's pretty good. A know it all Doctor treats his coworkers and everyone like trash but still gets results so he keeps his job. Definitely the weakest show on my list but nonetheless worth watching.
Hope you like em'
Cheers
Supernatural is amazing by far best tv series I've ever seen.
You may also like Game of Thrones and Dr. Who. I Don't know if you're into superheroes or not but Marvel's Agents of Sheild is a new tv show that's coming out relatively soon, no idea when that will be on Netflix though. But Supernatural I know for a fact is on Netflix, makes me wish I had Netflix!!
