My family watches this every year; in fact, it's the kids who ask to see it. The Snoopy/folding chair scene still cracks me up! As far as the use of "blockhead", "idiot", etc., keep in mind when this movie was made. While kids still use these words to each other today, you won't find these sorts of phrases in most of today's gentler cartoons. However, their use in this show makes a good talking point about how mean the words sound and how they hurt Charlie Brown. It also helps to make his (Charlie Brown's) character more sympathetic, and makes him easier to connect with than most other cartoon characters.
