I think that by this time in Adam Sandler's career, there are two kinds of fans: ones who either hate him, or love him. And to be blunt, his roles in most of his movies are not that great. For instance; playing the title character in "Happy Gilmore", he was a hockey/golf pro. In "The Waterboy" he played a retarted waterboy. And in "Little Nicky" he played the Devil's son. Now, all of these roles are not ones that we can relate to. But yet we still loved those films, and with good reason.
But in "Big Daddy", Sandler plays Sonny Koufax. What makes this role so much better is that there's a sense of love from within. When a young boy (Cole/Dylan Sprouse) is left outside his door, he takes him in and gives him a home. And for anyone who saw "Billy Madison" you see the irony here. Anyway, to make a long story short, it's the most well-rounded character he's every played. It's a movie that anyone can like, even if they don't like Adam Sandler. Grant it, he has the starring role, but he's with a great supporting cast. It includes Joey Lauren Adams, Jon Stewart and Rob Schneider, along with some Sandler-movie regulars. Joey is particularly good here. She provides more seriousness than most of his female co-stars from earlier films.
This movie is definetly a comedy--and it' a good one at that. But it has more than just stupid laughs. It's cute, it's sad, and it's something you shouldn't be able to hate. The movie may be around 3.5 stars, it's better than just three. The only reason it didn't get more is because of the ending. I didn't think much of the ending, but I guess it was fitting. Anyway, Adam Sandler does something in this movie that I hope continues for him; that being playing great roles. So watch this movie, whether you like Adam Sandler or not. It' a great film.
