Critic-proof film for Sandler's fans--the rest won't find anything to tempt them. He's 32-year-old slacker law-school grad Sonny Koufax, who's got a big Peter Pan complex, since he's incapable of assuming any adult responsibility. However, he does want to impress women, so he decides to go for the awww factor by becoming the guardian of his travelling-in-China roommate Kevin's (Stewart) heretofor unknown son, five-year-old Julian (Sprouse). He teaches the kid a number of disgusting traits and winds up bonding with the tyke (they have the same emotional IQ--how hard can it be?).
