Men in Black III

(PG-13) ★★★☆☆

They’re back, and the result is OK enough. Josh Brolin impersonating a young Tommy Lee Jones is worth the price of admission. Turns out, an alien serial killer Boris the Animal (Jemaine Clement) has traveled back in time to save an arm and avoid lunar prison. So Agent J (Will Smith) goes back in time to save the day. While the effort is entertaining enough, Smith and director Barry Sonnenfeld have lost a few steps over the years.
