When he passed away in 2002, I really miss his great TV programs, there is nothing that even comes close on Dutch television.
I always was taken on a ride when he was traveling around the world, making for instance beautiful island-trips or visits to mu-sea.
His driven passion, humor and charm made his presentations so very special.
When I started watching his TV-shows, there was no way of stopping, I was hooked.
I agree with logan5 who wrote above me about him, specially the DVD boxed sets who are out in the Netherlands, because they are far from complete.
I wish they would broadcast the total series again, I know that my DVD recorder will be running over hours.
