This movie easily places in my top 5 favorite Adam Sandler movies. Adam plays a nicer (less jerky of a guy than usual) guy, the rating helps keep the cursing down from more recent comedies, and the plot - though very predictable - is super delightful.
Basically Sandler is a guy named Skeeter who has lived in a hotel his whole life with his dad and sister. The hotel gets bought by a rich mogul and Skeeter is promised a position of power in the hotel one day. Unfortunately, he serves his entire life as the janitor of the hotel. The hotel changes hands to new management and this is when the story truly begins. Skeeter is places in charge of telling stories to his niece and nephew. He tells stories, and whatever the kids contribute to the story happens for real to Skeeter in the following day. So he gets his chance to become the new hotel manager, and uses the new storytime opportunity to weasel life enhancing story arcs from the little kids so his life can be better.
Everyone in the movie is great. Guy Pierce makes a great, more-or-less believable villain (teamed with Lucy Lawless), and Keri Russell is a good foil for a love interest. The story is cute and the bedtime stories that Sandler tells are full of good ol'e clean yet Sandler-esque humor. Russell Brand was a great surprise in the film (He's not in even one trailer), he's basically Skeeters friend that sleeps over and watches the kids every night, providing a very wavy opinion at every choice made in the story, in a hilarious way.
The film does a great job of lampooning the degree that schools and parents watch over what their kids eat nowadays, with Rice Crackers and Wheat Germ being all the kids have, and when it comes down to it, when the kids in the movie eat sugar, nothing bad happens, showing that sometimes people just need to lighten up and have a good time once in a while, knowing that little harm is going to come of a light unhealthy experience.
The only thing I did not like about the movie was the inclusion of an obnoxious CGI Guinea Pig named Bugsy (Cause he has HUGE eyes). He is there for a constantly absurd call back gag, and I have no idea why the kids insist on taking him everywhere they go. Other than that, the movie is well worth the trip to go see.
