Bad to the bone

The fourth season of “Gotham” will be based on “Batman: The Long Halloween” and “Batman: Year One,” with a heavy emphasis on the Scarecrow, who is decidedly more menacing than he was in “The Wizard of Oz.” And don’t be surprised if Harley Quinn shows up at some point.

The roots

Nobody has studied the comedy of Jerry Seinfeld more than Seinfeld himself. He puts his expertise to good use in “Jerry Before Seinfeld,” a sort-of stand-up special in which he revisits the jokes that put him on the map. It’s his first Netflix special since leaving Crackle to join the Netflix streaming empire.

Taking care of business

“Nathan for You” doesn’t officially start its fourth season until next week, but business consultant Nathan Fielder has never been one to follow convention. Thank goodness. “A Celebration,” which checks in with former clients/victims, reminds us how Fielder’s Einstein-in-the-headlights character has made him one of comedy’s sneakiest and winningest comedians.
