Yay!! Downton Abbey is back! Maggie Smith pulls some one-liners and we all win/
Love this show. :D I'll spare the details given 90% of this forum is male. But a good Brit-drama nonetheless.
My wife and I both like Downton Abbey. It's a good period piece with good acting.
As far as other series that my wife and I watch(ed): Mad Men, Breaking Bad, Walking Dead (she gets a little freaked out by the zombies), Lie to Me, The Office (stop watching after Steve left), early Family Guy, and Arrested Development. There are some that are popular that we haven't watched: Community, Sherlock, American Horror Story, Parks and Recreation, etc.
My favorite serious series is Breaking Bad. The early seasons of Family Guy cracked me up but I think my favorite comedic series has to be Arrested Development. Both are subject to change, however.
