Soon after “Love Island” premiered in Britain in 2015, the series — which followed a rotating cast of young, Instagram-attractive singles looking for love — became nightly appointment viewing during sweltering summers. “Love Island” follows hotties living in a tropical villa, where they go feral, are filmed 24 hours a day and couple (and recouple), on a show that’s broadcast six nights a week, typically over eight weeks. The arrival of “bombshells” — new sexy singles — causes romantic chaos as the cast members compete for a prize of 50,000 pounds, or about $65,000 (which viewers vote on), and perhaps a new significant other.
