Community (NBC, 8 p.m.) — I don’t know what’s going on here, but I like it.
Parks and Recreation (NBC, 8:30 p.m.) — Leslie’s efforts to take down the wall separating Eagleton and Pawnee yield unexpected results. I hope it’s not a wall, but THE Wall.
Suits (USA, 9 p.m.) — Season premiere. Suits up, put your Suits on, etc. etc. etc.
Sirens (USA, 10 p.m.) — Series premiere. Denis Leary adapted this British series about narcissistic EMTs who can’t save themselves…but CAN save their patients. You see, it’s ironic, or something.
Portlandia (IFC, 10 p.m.) — I’m honestly shocked it’s taken Portlandia this long to get around to calling an episode “Ecoterrorists.” (With Olivia Wilde!)
Review (10 p.m.) — Series premiere. What Danger said.
Scandal (ABC, 10 p.m.) — “Quinn wants to prove herself.” GOOD LUCK.
