Lauren Laverne is absolutely lovely. She can be funny, entertaining and likes good music, it's a no-brainer.
Unless you think the total opposite to this, which I do. (Actually, having never listened to her radio show due to my anger issues on hearing her stupid fucking voice, I've no idea what her taste in music is like, but the band she was in were really really dreadful).
Also, I don't expect this to be very good. As much as I enjoy Brooker and Mitchell, I've heard their spiel many many times before. I'm not sure this show is going to improve it much.
And as for a link to the trailer in the OP; are you kidding me? Was that really necessary, considering Ch4 have been advertising it between every single one of their programs for the last two weeks?
