I do not find her series funny, it seems she is taking the mick out of her characters life and sadly there are people who will see some of their own life in her show. Therefore as we all laugh at ourselves at some point , this is the attraction of her show in my opinion.
I thought the character she played in Not Going Out was spot on and provided a good foil to Lee Mack's character.
I do not think she is a bad comic actress.
Like Paddy McGuiness in Max and Paddy where he was lucky to get a part that showed him to be a funnier comic actor than comedian!
