The reviews for this were pretty bad, but I think that's mainly because the trailers made it seem like this was a comedy. In fact, this is more like a lighthearted romance with a few jokes, and there's nothing wrong with that, really. The life lessons are caricatured and not really shown with much subtlety, but they're well-chosen and pertinent to a lot of people, which means some people might really associate with the story. The plot itself is fairly relaxed and not all that original, but it makes for a very enjoyable movie to watch to just unwind. The fantastic location where this takes place definitely adds to that with some ridiculously beautiful and paradisiac spots and general atmospheres.
All in all, this is a great film to watch as a couple to just cool off. It won't get you to laugh that much, but you'll have fun nonetheless.
In as sentence:
Not that original or funny, but a great cast and a fantastic location end up making this film quite enjoyable despite its faults.
