I agree with the positive reviews below, such as the one from Natrhnoor Noor.
It's a funny, silly, and entertaining movie with some beautiful scenery. Sandler and Anuston have great and believable chemistry.
If you're looking for a fun, light-hearted comedy then you will enjoy watching this movie.
If you're looking for great writing and serious mystery, this isn't for you and you should choose a different movie.
