Here’s what’s happening in the world of television for Monday, February 4. All times are Eastern.
Top pick
Arrow (The CW, 8 p.m.): Tonight’s episode of the recently renewed Arrow is the show’s 150th (sidebar: Holy shit, that’s a lot of feeling conflicted about justice and vengeance and death and family and stuff). Naturally, the powers that be have chosen to celebrate that occasion by bringing in Frasier Crane to narrate an in-universe documentary about the exploits of Oliver Queen, Felicity Smoak, Dinah Drake, John Diggle, Not-Laurel Lance, and the rest of Arrow’s once-masked merrymakers.
