“Zombieland: Double Tap” is usually content to be funny on just one. Like the first episode, but even more so, this chapter is aware that zombies are a pop-culture cliché and is content to goof on that fact. There’s nothing here to rival the thing with Bill Murray in “Zombieland” — after all this time, it still feels like a spoiler to say much about it — but the performers commit to the silliness in a spirit of well-compensated affability. Nobody works too hard, including the new faces on hand to refresh the franchise. They include Rosario Dawson, Luke Wilson, Avan Jogia, Thomas Middleditch and Zoey Deutch.

Deutch is the principal scene stealer, playing Madison (it’s a “Zombieland” tradition that everyone has the name of an American city), who has survived the undead onslaught in the freezer of a shopping-mall frozen-yogurt store. Madison is blond and not very smart, and Deutch brings remarkable energy and wit to a dreary stereotype. Other satirical targets — Elvis, hippies — are about as fresh. But the zombie gore and the verbal pepper is sprayed quickly enough to keep boredom at bay.

“Zombieland: Double Tap” sets the bar low and steps easily over it, which makes it better than a lot of recent big-screen comedies. It doesn’t have much on its mind, but it isn’t completely brain-dead either.
