Re: What do you consider is the best film adaptation of a scifi book?
The SyFi Channel's Children of Dune
. I can't think of words big enough to describe this mini-series ... 'tis good! It was very satisfying and made every attempt at being faithful to the novels. By the way: for my money, 1984's DUNE is still The Cat's Meow.
