1) “The Bachelorette” finale, 8-10:01 p.m., ABC; concludes Tuesday. On the eve of the finale, we still see Hannah Brown, 24, (shown here) with three guys to choose from. Peter Weber, 27, is a pilot from California; Tyler Cameron, 26, is a contractor from Florida; Jed Wyatt, 25, is a singer-songwrier from Tennessee. Tonight, she dumps one and takes the others to meet her family. On Tuesday, we see her choice.
2) “The Big Bang Theory,” 9 p.m., CBS. For almost three weeks, TV’s best comedy has been on the shelf, buried by an avalanche of summer reality shows. Now it’s back on Mondays and (starting next week) Thursdays; it has a wonderful final story to tell as Sheldon and Amy grasp for a Nobel Prize. Tonight, there’s proof available that a prime competitor (Sean Astin) plagiarized in college.
3) “So You Think You Can Dance,” 9 p.m., Fox. The show finally has its top 20 dancers; now they get their next chances over the next two weeks. Tonight, each of the 10 women perform with one of the “all-stars”; next week, the guys have their turn.
4) “Grand Hotel,” 10:01 p.m., ABC. Increasingly annoyed by te neighboring hotel, Santiago decides to take things into his own ands. This can’t be a good thing.
5) “American Sniper” (2014), 8-11:05 p.m., AMC. Two films tonight were directed by Clint Eastwood; both are from true stories involving soldiers. This one is terrific, an Oscar-nominee for best movie, actor (Bradley Cooper) and more; the other is so-so. That’s “The 15:17 to Paris” (2018), at 9 p.m. on HBO2. The story – vacationing U.S. soldiers stop a terrorist on a train — is fine, but not enough to hang a movie on. Casting the real-life guys took away any chance for nuance … which Cooper delivers.
