TV Tonight: ‘Glee’ viewers pick 10 best songs for 100th episode

For its 100th episode, “Glee” goes with big — and familiar — music. Viewers chose the show’s 10 best songs; a reunion has people doing new versions of songs others did earlier.

Mel (J.K. Simmons) clearly has trust issues; he’s blind, but doesn’t trust his guide dog. Do we really expect him to trust his teen daughter Katie?

His ex-wife is more trusting, which may be a problem. (Did we mention that Katie is a teen-ager?) That leads to funny moments, in an episode that also has Henry get a glimpse at his friend’s family.

There are good reasons to resent this special — an hourlong commercial for Marvel movies, with other commercials tucked inside. People keep praising each other in hollow, actor-speak words. We’d be more upset, except that much of the praise is accurate: Marvel Comics had sold film rights to its top characters — Spider-Man, X-Men, Fantastic Four; it was building a studio with what one newspaper dubbed “second-string superheroes.” Then it soared. It hired Shakespeareans (Kenneth Branagh, Tom Hiddleston), an Oscar-winner (Gwyneth Paltrow), an offbeat star (Robert Downey Jr.). It mixed with slam-bang action, creating popular films that don’t need hollow praise.

Other choices include:

• 6:30 p.m., TruTV. Doubleheaders today and Wednesday will determine the last four teams in the NCAA tournament’s field of 64.

• 8 p.m., CBS. A bomb has exploded at a military charity concert. The team ponders if it was aimed at an old rock star (Keith Carradine) or was part of a broader plot.

• 9 p.m., CBS. When an undercover agent is killed, the team searches for a mole.

• 10 p.m., ABC. The main story — influencing a politician — is weak. A secondary one, tricking a reporter, has its moments because of the addition of Jaime Ray Newman of Farmington Hills as a scam artist.
