1) “BH90210” debut, 9 p.m. Fox; rerunning at 8 p.m. Friday. Summer is the time to try something odd, toying with TV’s reality. Fox does that Sundays (with “What Just Happened?”) and now has a new twist. Former “Beverly Hills, 90210” stars –Jennie Garth and Tori Spelling (shown here), plus Shannen Doherty, Jason Priestley, Brian Austin Green, Gabrielle Carteris and Ian Ziering – play versions of themselves. After a fan fest, they talk about rebooting the series. Soon, old feuds and romances are re-ignited.
2) “Bulletproof” debut, 8 p.m., CW. Noel Clarke and Ashley Walters are British actors with American tastes. They co-wrote and star in the opener, reflecting their fondness for “Bad Boys” and “Lethal Weapon.” Naturally, it has two frantic car chases and a foot chase, plus shooting, hitting and a boss who reminds them about “things called warrants – you know, papery, with words and things.” But it also includes personal moments, with two cops who have opposite lives. It’s a fairly good start.
3) “Hynotize Me” debut, 9 p.m., CW. A hypnotist brings four people onstage, giving them hypnotic suggestions. Then they have a task to do. The result is loud and loose and mostly just hectic. Host Taye Diggs appears to be inexplicably amused; then again, he’s a skilled actor.
4) “Love Island” and “Florida Girls” season-finales, 8 p.m., CBS and 10 and 10:30 p.m., Pop. One show is high-profile, already renewed for next summer; tonight, it names its winning couple. The other is an addictive little comedy about four dropouts in Florida. In this two-parter, they try to go ahead with Kaitlin’s island party, while Shelby frets about her GED test and more.
5) “Yellowstone,” 10 p.m., Paramount. First, this has great lead-ins — “Mom” reruns from 4-7:30 p.m., then “Top Gun” (1986) from 7:30 to 10. Then John (Kevin Costner), the ranch owner, has increasing ill-will with the Beck brothers. Also, his grandson gets his first horse.
