1) “The Bachelorette” finale, 8 p.m., ABC. The last two episodes have left the show in tatters. Michael Allio left to be with his son; then Greg Grippo left after he said he loves Katie Thurston (shown here) and she (vowing not to mention love until the finale) didn’t reciprocate. She wept in the bathroom and asked for a flight home. Now – barring her departure or Greg’s return – she has overnight dates with Blake Moynes and Justin Glaze, followed by a decision.
2) “American Ninja Warrior,” 8-10 p.m., NBC. Now that the Olympics have ended, NBC has a pile of new competition shows to air. “Ninja” (which reruns Friday) continues its semi-finals; “The Wall” follows at 10. Coming are: “America’s Got Talent,” Tuesday and Wednesday (repeating Saturday and Sunday); “College Bowl,” Tuesday; “Family Night Fight,” Wednesday; and “Making It,” Thursday.
3) “Reservation Dogs” debut, any time, Hulu. Here’s one of the summer’s best surprises – a neatly understated comedy-drama about four American Indian teens. Bear, 16, is a sweet kid who figures he’s the leader of this “gang.” Elena is the only one trusted with money; Willie Jack and Cheese are along for the ride. In the first two episodes, arriving today, they go big (stealing a truck) and small (selling meat pies). The other six episodes arrive weekly.
4) “Roswell, New Mexico,” 8 p.m., CW. All three sorta-siblings face turning points. Michael is consumed by rage … Max is confronted by Liz … and Isobel learns more about her powers. That’s followed by a new “Republic of Sarah,” with Sarah confronting her brother Danny.
5) “United States of Al,” 9:30 p.m., CBS. This comedy is only moderately funny, but offers some of the most likable characters on TV. In this rerun, the usually genial Al is filled with fear. He hasn’t heard from his family in Afghanistan; now he’s afraid something has happened to them.
