There something slightly off putting yet hilarious about men who refuse to grow up, and in these Peter Pan Syndrome movies, they make for great comedy fodder. These are the greatest arrested development movies, wherein the main character must grow up and come to terms with being an adult. Also known as most Adam Sandler movies. I've always found it interesting that most overage coming of age movies are also romantic comedies, signaling in some way that all a guy needs to want to grow up is a good woman. Hmmm. I left this list open, so feel free to add any I miss and vote up or down your favorites.
