When Politically Incorrect was on Comedy Central, it was excellent. It lasted an hour, fewer commercials, and CC was braver with whom they picked to sit in the 4 chairs. Bill was MUCH more palatable then - he wasn't "famous" and was still a geeky failed comedian/actor. He let the guests do the talking. Once ABC bought it, it all went to hell - including Bill. He became "famous", got a big head, and spent 1/3 of the show spewing out his crap.
If you want to see a great talk show, watch "So Graham Norton" on BBCA!
