I'll miss his work.
Update: Roger Ebert has a fantastic little essay about how he met McCarthy as a high school kid:
I met him so long ago. When I was new in my job at the Chicago Sun-Times, I got a letter one day from a high school kid who said he loved the movies and wanted to have a talk with me about them. The letter struck a note. I met Todd and his friend Charles Flynn at Andy's, a place with pretty good hamburgers, outside the back door of the Sun-Times.
They knew everything about the movies. They had seen them all, debated them all, written about half of them. They became for me examples of a species I thought of as "Doc Films Kids," named after Doc Films at the University of Chicago, the nation's oldest film society. Other Doc Films Kids included Dave Kehr, now at the New York Times. They'd seen so many movies I didn't see how it was possible in such brief lifetimes. Once at O'Rourke's, Flynn was telling me how much Otto Preminger hated over-the-shoulder shots, and I nodded wisely while asking myself, how in the hell does he know that?
There's more great stuff in there.
