Funny as ““The Daytrippers’’ is–especially when the clan’s pursuit of the elusive Louis leads them into the company of families even loopier than their own–the movie’s tone is ultimately more bittersweet than knee-slapping. Mottola knows all too well the maddeningly regressive dynamics of a family trapped too long in its own company. The characters may start as cartoons, but by the end our judgments about everyone have been revised and deepened. Thanks to the superb cast and Mottola’s deft touch, this modest-looking comedy proves quite memorable.
