7. Downton Abbey
Stars: Hugh Bonneville, Jessica Brown-Findlay, Laura Carmichael, Jim Carter, Brendan Coyle, Michelle Dockery, Siobhan Finneran, Joanne Froggatt, Thomas Howes
Period costumes, engagement drama, and polite decorum? We understand your reservations here. But this World War I drama is actually a deliciously soapy scandal, and the historically accurate trappings it's bound by only serve to keep the melodrama balanced and believably in line.
Much like Mad Men, it thoroughly transports you to another era, but unlike conflicted characters like Don and Pete, there is very little about British aristocracy that's actually relatable, and that's exactly the point. Think of it as a trip across the pond (and back in time) without the hefty airfare (or the DeLorean). And if anyone has anything to say about it, just claim you're in it for the history lesson and the lovely ladies.
Still on the fence? Maybe Kenny Powers' visit to Downton Abbey will convince you.
