We've started on the 4th season now; it's dangerous because Kelley has 12(!) of them on a disk that he downloaded. Seasons 1-3, we got through Netflix -- watch 3-4 eps, send the disk back and wait. But now we have so many it's hard to stop at one a night.
We watched Chuck vs. the Coup d'Etat last night; I love how Chuck prevented a nuclear war through impromptu couples counseling

And the continued references to Casey's past on Costa Grava were funny, too.
I enjoyed this show when they were doing the unfulfilled sexual tension thing, but I like it more now that it's been fulfilled
