Friends for life

A three-day “Sex and the City” marathon marking the show’s 20th anniversary gives cosmo-swilling viewers a chance to travel back to a time when they imagined Sarah Jessica Parker and Kim Cattrall were real-life besties and Cynthia Nixon was assumed to be too finicky to run for public office. The 94-episode run kicks off with a half-hour retrospective.

New kid in town

British comedian Romesh Ranganathan was practically unknown in the United States when he decided to move to Los Angeles. His attempt to start over is at the heart of “Just Another Immigrant,” a 10-part docu-series that mostly features the comic realizing he’s suddenly lower on the food chain than Pauly Shore. Ranganathan may deserve more love in America, but it’s hard to tell from the first couple of episodes whether he has the chops.

Stars among us

I’m not convinced “Mean Girls” or “SpongeBob SquarePants” will become timeless musicals, but those productions collected the most nominations for “The 72nd Annual Tony Awards,” hosted by Sara Bareilles and Josh Groban. Amy Schumer, Denzel Washington and Andrew Garfield offer eye candy for those who don’t give their regards to Broadway.
