I think this highly entertaining film is a bit better than Maltin gives it credit for being. More than just a light comedy about the travails of a summer vacation gone wrong, the movie has some hard edges that give it some bite. Among these are the frayed relationships between Hobbs and his elder daughters, the marital difficulties of one of them (bordering almost on being painful to watch), and the mutually hostile relationship of Hobbs with his grandson. Hobbs is no kindly buffoon; a well-meaning but irascible fellow, he has plenty of cutting and sarcastic comments for the family members that cause him so much grief, yet who he obviously cares for. There are some genuinely touching moments throughout the film, especially as Hobbs reconnects with his teen son. The script is excellent, with many sharp edges and plenty of crackling repartee. Stewart, in a fine performance, makes the movie; his expressive face completely reflects the frustrations, disasters, and surprises he encounters, as well as the warmth and pride he feels for his family. The brief narrative voiceovers he supplies (continuations of the letter he dictates at the beginning of the whole flashback movie) are well-placed and witty. Maureen O'Hara is perfect as the well-meaning Mrs. Hobbs. This is a thoroughly enjoyable 60's movie that stands up well to the passing years.
