too late for sons, which is on Tuesday nights at 10, American Horror Story Wednesday nights at 10...as far as everything else check out post #126. Strongly suggest renting box sets of previous seasons of stuff because a lot of this is worth seeing from the beginning. Sadly Terriers/Lights out(R.I.P.) are not yet available. If you want to see the show that started it all, The Shield is relatively cheap in the complete box set. Always Sunny has box sets and is still on Thursday nights...I think that's most of it. Oh yeah, first couple seasons of Damages on box sets too. Nip/Tuck as well if you really want to go back.
And you should, you really should.
