I thought seasons one and two of "Chappelle's Show" were very funny. Some skits weren't as good as others, of course, but most of the material was funnier than any modern "Saturday Night Live" episode.
After Chappelle left, I admired his reasoning - he was smart enough to avoid what a lot of other performers fell victim to: over-exposure. Comedy Central ate up Chappelle's Show after it broke records on DVD (highest-selling TV show DVD ever), and the exposure was beginning to become too much.
So with Dave refusing to reappear for another season, Comedy Central dug into their vaults for skits Dave HADN'T used on previous episodes. Then they hyped up these episodes more than anything I've ever seen before - I've even seen ads for the "Lost Episodes" here on IMDb! Sitting down tonight to watch the first of the "lost" (i.e. "stuff Dave didn't like") episodes, I knew it wouldn't be very good since Dave hadn't approved of the skits (hence why they were originally canned), but I didn't expect it to be quite as bad as it was. To be fair, I laughed at the revenge joke involving the man in the wheelchair getting thrown down the stairs (as cruel as it was) - but the rest was pretty lame. And what was with the commercials? The show was on less than a minute before they had another three-minute commercial break. It's obvious Comedy Central is milking it, fifteen minutes of the episode had passed before they had even aired the third skit of the show! I wasn't expecting much but I still found myself disappointed. They really milked this for all its worth and if Dave doesn't come back for a fourth season (and it doesn't look like he will), then it seems Comedy Central has decided to end "Chappelle's Show" on a low note.
