Pretty much faithful to the original and often beloved 1961 film of the same name that starred Hayley Mills in the dual sister roles along with Brian Keith and Maureen O'Hara, this remake essentially follows the same plot (with newly named characters and locales) and even clocks in at nearly the same, but still quite overlong, running length of a little more than two hours.
That said, it's not a great film by any means, but it still comes across as an enjoyable enough, although lightweight diversion that should at least partially please nearly everyone who sees it. Even so, the odds are that the fans of the original will like it more than the kids of today who may find the proceedings either too quaint (if they're older) or too restless (if they're younger).
Aside from the preposterous notion that serves as the story's catalyst -- of two parents splitting a set of identical twins at birth with each taking one and never even trying to contact the other for more than a decade -- the plot is serviceable but nothing outstanding. Nonetheless, the writing/directing/producing team of Nancy Meyers and Charles Shyer (the "Father of the Bride" movies, "Private Benjamin") have included enough funny, charming, and occasionally heartfelt moments to please all but the most hardened of cynics.
It's nice to see a pro-family movie, especially one where the kids obviously love and praise their parents and wish for them to be one big, happy family. Most kids should easily get that message beyond all of the hijinks and kid-oriented material that occur, but the film's length of a little more than two hours might prove restless, especially for younger ones. Likewise, adults may find themselves wishing the film were at least a half hour shorter, as the film tends to get a bit tedious particularly as the proceedings draw to a close.
Even so, you can't help but like this charming little film that feels like a throwback to those pictures the Disney studios used to make (when compared to the more hyped up recent remakes of their other live action pictures). While way too long and lacking in originality or surprises, the winning performances and overall charm the film easily exudes makes it a worthwhile antidote for moviegoers looking for a decent family film.
The film gets a bad grade, however, in the supplemental materials category with its theatrical trailer being the sole inclusion of such material.
