Sword of Truth is more or less a template ripoff of Wheel of Time. Terry Goodkind's pontiferous narration might be a turn off, but the series sucessfully stands on its own because it is significantly bloodier and the characters mature with the passage of time unlike with WoT where even the adults tend to be eternally undecisive or rebellious teenagers.
Sword of Truth was adapted into a tv series. Kahlan wasn't as elegantly beautiful and Richard wasn't as heroically buff. Still, it was a fairly okay adaptation.
A Song of Ice and Fire was adapted into the Game of Thrones. The food porn was pretty much removed to make room for more porn. It's quite the afaptation. George R. R. Martin is pleased, anyway.
If anyone has ever seen the impractical requisites of the late Robert Jordan, they won't wonder why WoT didn't get an adaptation while he was alive.
There was a time I was wishing for a multimedia trilogy. The first would be a book to introduce the characters and their stories. The second would be a comic to provide visual affirmation to the readers's imaginings. The third would be a limited run movie to wrap it up and we get to hear the characters for the first and last time.
edit:
@Moctemma, this was a pre-Y2K wish, before COBOL became a scapegoat and I became a blacksheep.
