Go On 9 p.m., Channel 7
It’s a full-fledged “Friends” reunion, with the entire gang except Jennifer Aniston, Matt LeBlanc, Lisa Kudrow, and David Schwimmer. That’s right, it’s Matthew Perry and Courteney Cox (pictured) — Chandler and Monica — appearing together on Perry’s show. She plays a recent widow Ryan wants to date, but the plot thickens when wingman Anne starts to compete with him for her attentions. There’s a lot of good stuff in this show, and yet it’s less than addictive and the ratings show that. Right now, “Go On” is, as they say, on the bubble.
