I certainly do! I remember scenes/sequences in his MS&T/Otherland novels that sent utter chills down my spine and sometimes quite honestly kept me up at night! This is one of the many things I love about Tad Williams, and personally I think he would be terrific as a horror author.
Anyone else here feel the same way I do?

Personally I think Tad Williams to be an underated author. The first thing of his I read was The Dragonbone Chair, and even now that series sits on the bookcase downstairs where it can be easily grabbed for a quick reread. His turn of phrase and descriptions are excellent.
