‘Think Like a Man’ delivers

Gabrielle Union plays Kristen in the very funny relationship movie “Think Like a Man.”

A humorous self-help relationship book becomes an amusing and often biting take on the war between the sexes with “Think Like a Man,” based on comic polymath Steve Harvey’s “Act Like a Lady, Think Like a Man.”

Funny people in funny situations deliver funny lines with, thanks to director Tim Story, zippy timing in this somewhat overlong but still hilarious romp through the world of “Players,” “Mama’s Boys” and “90-Day-Rule Girls.”

The script, by the guys who gave us the equally smart and sassy “Friends With Benefits,” follows four women with man problems and four guys who are the “types” creating those problems.

It lets the women (Gabrielle Union, Taraji P. Henson, Regina Hall and Meagan Good) discover Harvey’s best seller and start putting its tips to use. Mainly, “control the cookies” — as in, don’t be quick to jump in the sack and grant the man access to “the cookie jar.”

Mya (Good) tries to get “the Player” (Romany Malco) to be patient and respect her. Kristen (Union) tries to make her beau since college, a toy-and-movie poster-collecting fanboy “Non-commiter” (Jerry Ferrara), grow up and propose. “The Dreamer” (Michael Ealy), a would-be chef, has to hide his income and employment status from “the Woman Who is Her Own Man,” high-powered businesswoman Lauren (Henson).

Single mom Candace (Hall) tries to figure out if “Mama’s boy” Mike (Terrence J) can be pried from his mother’s clutches.

And here’s Harvey, seen on a TV interview in one scene and at other times speaking directly to the camera, laying out the blunt advice.

“Don’t hate the player. Change the game.”

“Men respect women who have standards.”

Biting banter rules the day with this ensemble, with Keith Merryman and David Newman peppering the script with Harveyisms and hilarious cracks about everything from “Star Trek” and Oprah to that “traitor” to men, Harvey.
