It's a bit of both if I'm being honest. SPN is on more often than Doctor Who (since it has almost twice as many eps a season) and it's had better quality episodes lately imo, but at the same time Doctor Who came first and helped build so many friendships. Honestly, I think it's a tie between them right now. I go through phases of loving things the most anyway.
ah, nothing like listening to MCR albums and screaming over spoilers for the next season of your favorite show things are looking good, both in general AND for me, hehe 50 left
