TULSA, OK— Science-fiction fans Pete Carver and Matthew Wynne disagreed sharply Monday on the relative merits of Harry Potter And The Sorcerer's Stone and The Fellowship Of The Ring, neither of which hits theaters for months. "The storyboards for the Quidditch tournament I saw on this one web site look terrible," said the pro-Tolkien Carver. "There's no way that scene can be better than I've heard the Balrog one is." Wynne countered that the set design for the Great Hall of Hogwarts set "will completely blow away" that of the Mines of Moria.
