There's not an original idea in the new family holiday comedy Unaccompanied Minors. Screenwriters Jacob Meszaros and Mya Stark simply mix and match elements from movies that have come before it, dipping into the John Hughes' oeuvre in particular to borrow liberally from the Home Alone movies and The Breakfast Club. But those are not bad sources for something like this. This is not a film swinging for Oscars; it simply wants to provide families with some old-fashioned escapist entertainment. Sure, it's formulaic, but as undemanding fun, it works beautifully.
