(MCT) — Josh Brolin impersonating the young Tommy Lee Jones is worth the price of admission to “Men in Black 3.” Dry, drawling, deadpan — he nails the flinty Texan in this sentimental sequel to the sci-fi comedies about secret agents in black suits who save the world from aliens.

We have to meet the young Agent K because an alien serial killer who isn’t fond of his nickname, “Boris the Animal” (Jemaine Clement), has traveled back in time to save the arm that Agent K shot off in 1969, and avoid the 40-year prison sentence that followed.
