These are the 7 most famous fandoms here (Plus, my all time favorite I had to add Friends!)
If you want any other else to be first add it :D

this ,OUAT & GA the most<3 . (ofc HIMYM too!)

TVD ! Can you add The Originals ?

Could you please add The Hunger Games and Teen Wolf?

Lost ♥♥♥ I know not everyone watched it, but it's my favorite so i have to suggest it!

Other suggestions:

Like Fatemeh said - Teen Wolf!!! && THG - i think a good portion of the family read the books &/or watches the movies!

Private Practice
Shameless
Skins
True Blood
The Big Bang Theory
Buffy The Vampire Slayer
Dawson's Creek
Gossip Girl
Smallville
Supernatural
Veronica Mars
Bones
Glee
Twilight

You could also include Nikita a lot of members do watch it ;) I agree with the list of Holly also ;) Maybe DH (don't know if you are numerous for that one though ), Gossip Girl, Gilmore Girls and The OC :)

I'm going to add THG, TW, Nikita, Skins, Gossip Girl, SPN, VM & Glee in the next round ;-)

And guys Im not sure about the originals! I could include the. As a different fandom but i don't think that a countdown of TVD/TO would work since a lot people watch TVD but only a few watch TO!

MY FAVORITE THING EVER PLLEEEASSEE <333

^Nic,you could add TVD and The Originals together,it would be easier ^^

But please tell me all of them will happen eventually :D

But yeah I agree to add Teen Wolf, Hunger Games & Veronica Mars. I would want Gilmore Girls as well but I doubt many people watch it :/

^I totally agree for TO & TVD together, no need to do them separately
