Happy Friday! In this week's installment of Ask Alan, I try to tackle the impossible question of selecting four shows for NBC's scripted Mt. Rushmore, talk a bit more about my defense of the episode column and why some Netflix shows are slogs, try to put this season of "The Leftovers" into a historical context, and throw in one or two shameless plugs for a certain book that is on back order at Amazon but available again very very soon.

You can watch that in the video embedded both above and below; whichever makes you happier.

As always, you can send questions to askalan@hitfix.com, and the more tightly-worded, the better.

Alan Sepinwall has been reviewing television since the mid-'90s, first for Tony Soprano's hometown paper, The Star-Ledger, and now for HitFix. His new book, "TV (The Book)" about the 100 greatest shows of all time, is available now. He can be reached at sepinwall@hitfix.com
