People, People. Let us remember the reason fiction movies are made in the first place......entertainment. Were you entertained? I saw this movie with my family - let me start with my kids impression: they loved it, and watched it several times at their request.....mission accomplished. Next, my impression: Very entertaining (misssion accomplished again), and the "adult" jokes and references were adult enough where only adults and adolescents were old enough to understand them - no harm done. Overall, I thought it was an great movie. Did I rent it for the sound quality? No. If I wanted sound quality I would have put in T2, Matrix or some other high tech movie that you expect great sound from. DD 5.1 is not so bad either, maybe you need a better sound system...... I do agree that widescreen is better than letterbox, but again, sound should not be your major interest when there is a much higher level of message being sent to you from the writers, producers and directors.
See ya!
