Who is Thaddeus Bristol from Holidays on Ice and what is their importance?

Thaddeus Bristol is a discriminating theatre critic, who abhors the Christmas season and the scads of rote middle and elementary-school pageants that the season brings. He is perfectly willing to skewer the efforts of preadolescent actors and directors, because he believes that too many parents encourage their children to pursue interests for which they have no talent. Bristol will notify the children of their lack of talent, and seems to enjoy thoroughly dissecting the flaws and shortcomings of multiple amateur productions.
