The hit rate gets better as the film lumbers along and the scenarios grow more extreme, but it takes a certain degree of perseverance to roll with this thing until it pays off.
Lacking real zest or fun, it’s a middling effort, if one with ample heart and good intentions, that happens to star two actors who can rise to the occasion when necessary. Working together, it’s a shame that they serve both as this frustratingly mediocre comedy’s most reliable pleasure and most consistent disappointment.
