Love is in the air

You may know Laura Benanti for her killer impression of Melania Trump on “The Late Show With Stephen Colbert” and Zachary Levi for the TV series “Chuck,” but “Great Performances: She Loves Me” lets them show off their musical chops.

Something completely different

Viewers need only the tiniest bit of familiarity with Angela Merkel and Judi Dench to appreciate how splendidly they’re sent up in “Tracey Ullman’s Show,” which returns for a second season of fast-paced, positively silly sketch comedy. Ullman continues to be a force of nature, committing herself fully to each uniquely shaped character. Now if only the series would scrap its wholly unnecessary laugh track.

Bloody Sunday

If any TV show could use a few musical numbers, it’d be “The Walking Dead,” the relentlessly violent hit that keeps finding innovative ways to churn viewers’ stomachs. This new season promises more jam-packed action, which hopefully will come at us so rapidly there won’t be time to dwell on the eyeball dangling from the latest victim’s socket.

8 p.m. Sunday, AMC
