In no particular order:
Doctor Who

There's a spin-off called Torchwood (anagram for Doctor Who) and it's good but I don't like it as much.
Vampire Diaries

(And btw there are many hot guys in this!!!)
There's also a spin-off called The Originals but you CANNOT watch it until you've reached the end of season 4 of Vampire Diaries. Major spoilers!!!
Pretty Little Liars

One word of advice, I honestly would take your time with this one so you don't have to wait for the next season.
The cliff hanger...
There's also a spin-off called Ravenswood but I have not watched it yet but I've heard great things about it.
Supernatural

If you love anything and everything supernatural like vampires, ghosts, etc then this is definitely a show for you. There are a number of funny episodes and really scary episodes so you're warned. The story-line is great but it changes depending which season.
Teen Wolf
This show takes a while to get used too. The acting in the first episode isn't the greatest but the first episode of anything is always bad. When they turn into wolves the make up is so badly done it's kind of funny but I just somehow got hooked to this show and couldn't stop watching it. I recommend it but you won't necessarily like it.
Sherlock

Breaking Bad

I absolutely love this show and I recommend it but I advice you ask your parents first.
Game of Thrones

The Walking Dead

If you can't handle gore and a lot of jump-scares then this show is not for you. But of course if you want to scare the hell outta you then go ahead. Your funeral.
So this is a list of shows that I've been watching this year. The next show I want to try is Revenge as I've heard so many good things about it. If you have any suggestions please leave a comment and tell me what you think.
See you next time!
