Not only is the movie great (I'm a guy who's favorite actor is Vin Diesel) and very funny, the score is a mind blower. I really liked the score and how Debney went with a more emotional theme, rather than the techno theme at the beginning of the film and score. During the end of the movie (I admit this with some shame) I actually got misty when Lou is pulled out of the factory and is thought to be dead. The music helped this along(go back and click on the last audio sample for this theme) and I remember thinking "Thank God I didn't watch this with my girlfriend!" The score is a knock-out of funny cues and heartwarming themes. Lou's theme will go in my book as one of the best children's cue since John William's Home Alone theme.
PS. The Last track on the score is a cue from Powell's/Gregson-Williams' Chicken Run. It works with the movie.
