1) “iZombie” series finale, 8 p.m., CW. For the second straight night, CW ends one of its best shows. On Wednesday, it was “Jane the Virgin”; tonight is “iZombie.” Both are bright-looking, with a smart and likeable woman at the core; only one, however, has someone munch the brains of murder victim, hoping to absorb memories and attitudes. That’s Liv (shown here), a doctor and inadvertent zombie who works in the morgue and helps police. Now she has a bigger goal — preventing a war between humans and zombies.
2) Football, 8 p.m. ET, NBC. Really, it’s football season … sort of. This is the Hall of Fame game, which annually starts the pros’ pre-season. It has the Atlanta Falcons and Denver Broncos, in Canton, Ohio. They had so-so records (7-9 and 6-10 respectively) last year … which doesn’t really matter, because starters won’t be in there for long. But at least it’s football.
3) “Reef Break,” 10 p.m., ABC. How can you keep finding new crimes on a tropical island? Sometimes, new scoundrels simply land there. Tonight, a highjacked plane descends; Cat (Poppy Montgomery) rushes to try to save the passengers.
4) “Elementary,” 10 p.m., CBS. John Noble, who was the brilliant “Fringe” star, is back as Morland Holmes. His son Sherlock doesn’t really like him, but now they must link to battle the crime-prevention system created by tech billionaire Odin Reichenbach.
5) Food, food, food. When did food become an endless competition? The Food Network concludes “Chopped” at 8 p.m.; then Bobby Flay faces his friend Michael Symon in “BBQ Brawl” at 9 and has his “Beat Bobby Flay” from 10 to midnight. At the same time, “Family Food Fight” (9 p.m. on ABC) has families compete in “game-day drilling.” Ayesha Curry has seen plenty of game days as the wife of pro basketball star Steph Curry.
