The movie is a formulaic Hollywood RomCom production starring Jennifer Aniston and Adam Sandler. Saturday Night Live's presence is here too with Rachel Dratch and Kevin Nelon also playing roles and the general sensibility in this farce borrows a lot from their approach.
The premise is the complications that come from basing your life on lies to get what you want. Naturally humorous situations ensue as the house of cards is maintained at great expense. The problem is that sincerity of any sort is as rare as hen's teeth, and when it happens, they key the sappy music and you know that this is where they are supposed to touch your heart.
It is all so manipulative that its a big turn off. The natural humanity of the likeable players manages to keep this from being a total loss, but I wouldn't waste my time. This is a fine example of the kind of movie this writer wants to avoid. Live and Loin.
