Favorite (non-Christmas) TV series to watch with teens and adult kids?

Well, there have been some pretty successful American versions of British shows, such as All in the Family (Till Death Do Us Part) and Sanford & Son (Steptoe & Son). And many mainstream U.S. viewers won’t seek out a U.K. version (or even know it exists), so TV execs figure there’s no reason not to use a good concept. The U.S. version of Ghosts is nicely done, but I’ll try to check out the U.K. one. We’re not averse to British TV — lived in London for four years and enjoyed a lot of it before, during and since. (Some of it is dreadful, though, like Are You Being Served — being British doesn’t automatically mean high quality.)
