Christmas with the Kranks is technically a bad movie, but I love watching it every year near Christmas.
In terms of film making, it's passable I suppose. The shots are nice, and the acting is okay. The screenplay doesn't make much sense, and the tone shifts are blatantly terrible, but it's imbued with a strong charm and warmth that makes the mistakes seem somewhat part of the experience.
I'll never quite know why the characters are so obsessed with The Kranks missing Christmas, and why Tim Allen is so antagonistic throughout the entire film, but the sheer magnitude of incomprehensibility that permeates the entire film is so much fun to laugh at.
I don't know what else to say. This is a guilty pleasure for me. It's bad, but I love it so much.
