A total train wreck, this patronizing comedy from Walt Becker (Wild Hogs) stars John Travolta and Robin Williams as two businessmen, both pushing 60, who get stuck babysitting a pair of seven-year-old twins. Most of the jokes revolve around old people, gay people, and various bodily functions. Especially painful is a CGI sequence in which a medication mix-up leaves Travolta’s smile contorted into a Joker-like rictus; it’s an unfortunate reminder of the face-lifts many stars undergo in order to keep working in garbage like this. PG, 88 min.
