Humor for dummies

“The History of  Comedy” may be launching its second semester, but it’s still a beginner’s course aimed at viewers who get their laughs from Bazooka gum wrappers. Despite the rather obvious observations, it’s fun to watch Steve Martin, Rachel Bloom and others play professor as the course focuses on sex, animation and comedic duos.

What a concept

“Robin Williams: Come Inside My Mind” is the perfect companion piece to Dave Itzkoff’s recent biography of the late comedian, with the emphasis on great clips rather than analysis.

Wrongful ‘Suits’

“Suits” has lost its princess — and its sense of fun. The long-running lawyers-in-love series hopes to carry on without lead actor Patrick J. Abrams and the newest member of Britain’s royal family, Meghan Markle, by bringing on Katherine Heigl as a “formidable” attorney. Judging from the first two episodes of Season 8, the would-be rom-com queen fails to click as a tough cookie; she’s more a candied apple. The former “Grey’s Anatomy” star isn’t helped by writers who may still be drunk from Markle’s nuptials. It’s time to put “Suits” in storage.
