It's progress of sorts that Adam Sandler's latest is merely vapid, not another affront to cinema. After single parents Jim (Sandler) and Lauren (Drew Barrymore) suffer a bad blind date, a plot contrivance thrusts them and their respective children together on an African vacation resort for blended families. As regrettably expected, there's plenty of vulgar and ethnic humor, although none that sends you scampering for the exit. Yet there are also weighty issues at play, from adolescent maturation to marital infidelity to the death of a parent or spouse. The easy chemistry between Sandler and Barrymore, who previously squared off in The Wedding Singer and 50 First Dates, keeps the film afloat.
