I much preferred Kirstie Alley and her character. "Cheers" really took off for me when they got rid of the dull Sam/Diane storyline (and Diane's whiny voice
) and started to develop the other characters.
Series one was essentially about Gavin and Stacey, series 2 more about Smiffy and Nessa and, I thought, series 3 (coming out of the brilliant Christmas episode) expanded and included a little more of the other characters - as in Pete and Dawn's 'wedding'.
