When your movie gets riotous laughter out of endless utterances of the word "Focker," it doesn't have to try very hard, and this sequel to the 2000 hit Meet the Parents barely breaks a sweat. When in doubt, after all, just have someone refer to Ben Stiller's character by his real name (it's not Greg, but Gaylord Focker) or to uncle Dom Focker and cousins Randy Focker and Orny Focker. The first movie, a rickety Rube Goldberg contraption of slapstick and disquiet, featured Robert De Niro torturing Ben Stiller, and he relished the part; here, being tortured by Greg's hot-for-each-other folks, played by Dustin Hoffman and Barbra Streisand, he's not having as much fun. His loss: Hoffman and Streisand are having such a swell time as Roz and Bernie Focker that they seem to be in an entirely different movie -- a funnier one, a sexier and smarter one. The Fockers deserve their own sequel, and just leave those other fuckers out.
