This is Roger Ebert's blog entry regarding his departure from At The Movies.
This was truly a landmark television show for a bundle of reasons, not the least of which that it was so damned entertaining for so many years. When I was younger, I tried to watch this every week to see what Gene and Roger were saying about the new films I probably wouldn't see.
Also fascinating in the post are the two YouTube clips at the end, featuring some truly vicious barbs thrown back and forth between Siskel and Ebert.
