Watched the specials, the series, read the comics, etc. Still watch them, too. My Mom made hooked rug wall hangings of Linus and Lucy for my brother and me (this was back in 1981). Was also in a production of "You're a Good Man, Charlie Brown" when I was in high school - I played Lucy. My old castmates and I still toss the few lines we remember at each other sometimes.
The innocence and subtlety are what made it special. It was a rather sad day when Mr. Schulz finally passed on.
