"[T]he perfectly cast Brolin conveys hints of playfulness and warmth while staying true to the craggy stoicism at the characters core."
A.V. Club "[Sonnenfeld] has recovered some of the brashness and all of the unbridled affection for the weird, wonky otherworldly types that made the initial 1997 cosmic comedy such a kick."
Los Angeles Times "Among the many pleasures of MEN IN BLACK 3 is the nimble efficiency with which the movie reestablishes the old MIB conventions -- all those fabulously ornate Rick Baker-designed creatures, all that Jones crustiness and Smith slickness..." -- Grade: A-
Entertainment Weekly 3 stars out of 4 -- "It has an ingenious plot, bizarre monsters, audacious cliff-hanging...and a closing scene that adds a new and sort of touching dimension to the characters of J and K."
Chicago Sun-Times "[I]t's Josh Brolin, as the young Tommy Lee Jones, who steals MEN IN BLACK 3....He channels Jones' mannerisms, nails his Texan drawl and even rather eerily resembles the actor..."
USA Today "What works, like comic hellfire, is the casting of Josh Brolin as the young Agent K. Brolin's take on Jones' deadpan delivery is spot-on and spectacularly funny."
Rolling Stone 3 stars out of 5 -- "Brolin is an excellent, unflappable replacement for Jones."
Box Office "[Featuring] the jewel tones of Bill Pope's appealing cinematography. Other production elements, like Danny Elfman's score, continue the winning look and feel established in the first film."
