I should note that my list above is what I have on DVD.
Most of what I watch is downloaded (only way to get shows from back home around here without waiting until Christmas!) so I've got several hundred gigs of various shows from the past few years - Entourage, True Blood, House, Walking Dead, Prison Break, Shameless US, The Big C, Mad Men, Flashforward, Jericho, Game of Thrones, Rubicon, a few more I can't remember right now.
Would recommend any of those (except only seasons 1-2 of Prison Break)
