I heard a chav on the bus with a Catherine Tate ring tone the other day. She then preceeded to talk about her drug habit and selling her stuff she nicked from Dixons...these are the type of people Tate appeals to.
The the same jokes are repeated in every episode and no real thought or wit has gone into the writing of this show. Catherine Tate writes like an idiot for an audience of idiots. If you want a well written and intelligent comedy, delivering wit and satire of culturally and socially relevant material...you're in the wrong place, you need Peep Show.
