I remember watching this as a child, and I loved it greatly during that time. As an adult, looking back I can see the humor being a tiny bit dated. Adam Sandler's typical humor was a lot funnier during this time. Still, watching it in 2015 I can easily say it's one of my favorite holiday themed movies.
The movie is essentially what you'd get if more shows/movies highlighted the village idiot's life currently, but in a musical fashion to get people at least slightly moving to the tunes. As a musical, it's a bit.. Lacking in memorable tunes, but I can't deny that Sandler's voice is definitely memorable in this movie, whether it be in a parody-like voice, or his own, he does it pretty well.
Story-wise, it's what I originally said, a village idiot getting more of a backstory and plot. Davey Stone is a mess of a man that has wreaked havoc amongst the public quite a lot, more specifically around the holidays. It's not until Whitey Duvall comes to Stone's rescue in court that he's even saved from jail time. Over the course of the movie, more characters get introduced including Jennifer(Stone's love interest.), Benjamin(Jennifer's son.), and Eleanore(Whitey's sister.). They play a role in the development of Stone's character, making us see a human side of this careless wreck.
Overall, the movie really builds, while it's the same typical humor(I know I said this earlier.), it still holds a candle in the plethora of Adam Sandler films that were kinda good. Moments did feel like it dragged out, and there's a specific scene where you kinda question Whitey and Eleanore for not leaving well enough alone in terms of Davey's past. Despite that, it's a good film for Adam Sandler fans, one that you should put in their stockings this holiday if you know a fan that's yet to see this film.
