Portlandia 10 p.m., IFC

It’s back for another season of artisanal humor, with 10 new episodes. Carrie Brownstein and Fred Armisen (above) have come up with a wonderfully droll and affectionate series about a city and its unique culture. I love the show, despite its hit-or-miss quality. Some of the sketches — the “cacao” and the Aimee Mann bits — are unforgettable. Guests this season will include Roseanne Barr, Rose Byrne, Bill Hader, J Mascis, and Chloe Sevigny as Fred and Carrie’s new roommate.
