I will echo the above posts, the show can be extremely choppy at times. Big lulls of entertainment-lag. However, and this is a big however, wasn't Conan under the same scrutiny at the start? My memory is hazy on this, but it seemed like it took a year or two for Conan to gain an audience. I may be wrong on this, so please correct me if that is the case. (perhaps it is just the mechanics of changing a host, the newcomer has to live up to the former host, and that can be daunting...Conan may well be up against this when he starts Tonight.) While David will most likely suffer curiousity ratings slippage from Conan, he is in a really GOOD position, IMO.
