Will Smith and Tommy Lee Jones reprise their roles as Agents J and K in Men in Black 3. I really enjoyed the first two movies, although some of the aliens were slimey and icky. The lines are always good in these films - very clever, funny, witty. This one was more about the relationship between the two agents. Josh Brolin plays a younger Agent K who J meets when he has to go back in time to solve a little issue. It was very good. I did not see it in 3D - I don't really know if that is necessary. I really liked it.
