You’re a middle-aged couple with kids, circa 2010. Sleep deprived, overscheduled, striving, always striving, to keep up with whatever. You make time for each other because you know you’re supposed to. You drag your tired asses to T.G. O’Tuesday’s and pretend you’re having a date, but you’re really conducting a dinner meeting to plan the rest of your go-through-the-motions week/month/life. But then there are some funny, exciting, unexpected moments that make it all seem worthwhile. If that’s the case, you’re either the stars of the predictable-yet-entertaining “Date Night,” or you’re the people who are going to rent it this weekend.
