 Kelsey Grammer acknowledged the creative lull, saying that over the course of two later seasons, the show "took itself too seriously".Commentators do, however, acknowledge that there was an improvement following the return of the writers Christopher Lloyd and Joe Keenan, although not necessarily to its earlier high standards.Writing about the first season, John O'Connor described "Frasier" as being a relatively unoriginal concept, but said that it was generally a "splendid act,” while Tucker thought that the second season benefited greatly from a mix of "high and low humor.” Tucker's comment is referring to what Grammer described as a rule of the series that the show should not play down to its audience.
