I'm aware enough of Adam Sandler's style of comedy to not be too surprised by the crass, base humor that started this film.
His character is a jerk, blessed with his health, a good job and lovely family. He appreciates very little of it, and is a workaholic determined to make partner at his firm. In a quest to make life easier, he goes to Bed, Bath, and Beyond to get a new universal remote, which is given to him by Christopher Walken. (Does a character name really matter here? Of course not, it's Walken.) While the crassness continues - there's a recurring theme of the dog in lust with a stuffed duck throughout the movie - it slowly turns to realizing how he fast forwards through the important parts of his life. We all do, to some degree, we just don't have Christopher Walken to blame for it.
If the original of It's A Wonderful Life is too saccharine sweet and old fashioned for you, this movie with the same idea but more modern in both setting and behavior may appeal. I put it on to play in the background while doing chores and was surprised how good it turned out to be. With supporting actors like The Hoff, Sean Astin, Rob Schneider, and more, it's more entertaining and has more heart than I expected. Plus dog humping jokes.
