It made me not want to watch it. It looked like yet another "edgy" comedy show where the politically incorrect or just plain gross sketches make you uncomfortable. Turns out that the character featured in the advert (Gilbert) was one of her most likable, cute and amusing characters.
In fact most of Morgana's sketches and impressions were light-hearted cute fun and none of the characters were disgusting or going for the gross-out factor! There were no sexual jokes, which I found really surprising from channel four, I didn't feel uncomfortable at any point, I liked her a lot!
The talked about Fearne Cotton impression especially good.
