I'm glad you enjoyed it - so did I. Yes, it does seem like a great blow to a great many people, really, and I agree it's probably down to the fact that in all of Doctor Who there was only one character like the Brigadier, and he was simply excellently portrayed. For a character that was, let us be honest, so often badly-written or written one-dimensionally in some of the late Three stories, he was always well played, with a lot of charm and subtlety, by Courtney. I think a lot of what makes the character so likeable and memorable in this case comes from the actor rather than many of the scripts.
