If I remember correctly, the First Season of Frazier pales in comparison to the latter progressions. So does the First Season of Simpsons. They probably hasn't gotten the right mix yet for Joey.
I remember Frazier's special features on the First Season explaining that the only thing they took from Cheers is the character's name, wife son. Everything else they reinvented for the new series. As everyone knows Frazier is not a central character in Cheers.
I haven't seen Joey yet. The material to start with has been beaten to death in Friends and unless they come up with something fresh, this will really be a short series
