Welcome back, Arrow

Introducing Endless Mode: A New Games & Anime Site from Paste
Here’s what’s happening in the world of television for Monday, January 21. All times are Eastern.
Top pick
Arrow (The CW, 8 p.m.): When Arrow finished its sixth season last year, it felt as though its best days were behind it. The villains were all starting to sound the same. Oliver had the same revelations over and over again. The new members of Team Arrow became the founders of Not Team Arrow in a storyline that, shall we say, failed to inspire confidence. But a new showrunner and some time away seem to have done the denizens of Star City some good, because in season seven, Arrow seems to have entered a whole new era. (Arr-a? Anybody? No? Okay.)
