In the 10 years since the last Men in Black movie, Tommy Lee Jones has played everyone from a wizened small-town sheriff to a downsized white-collar worker, so policing aliens really isn't his thing these days. So most of the heavy lifting in Men in Black III lands on the sturdy shoulders of Josh Brolin as a younger Agent K, whom Agent J (Will Smith, who hasn't aged a day) travels back to 1969 to save.
That's the plot. But like the other two movies in the series, III is mostly an excuse for some fancy special effects and state-of-the-art CGI to strut their stuff, now in 3D.
Brolin brings some much-needed new blood to the franchise, but the movie plods along, time-warping the action back 40-plus years without much purpose. Plus, nobody seems to be having much fun. Where's a neuralyzer when you need one? --Michael Gallucci
