Bachelor In Paradise (ABC, 8 p.m.) — Series premiere. Rejected bachelors and bachelorettes from previous seasons return to try to find love before inevitably failing and opening up another bottle of wine at 2:13 a.m. by their lonesome. Summer TV!
Partners (FX, 9 p.m.) — Series premiere. I still don’t believe it’s real.
Running Wild with Bear Grylls (NBC, 8 p.m.) — Bear takes Ben Stiller into the rugged mountains of the Isle of Skye in Northern Scotland. Then they F*CK (probably).
Gravity Falls (DisneyXD, 9:30 p.m.) — The scheduling for this superb animated show is a nightmare, but if you can find it, it’s worth watching.
