I just watched it for the first time.
Very very good and interesting.
My least favourite character is the sideburns sunglasses man. Joel maybe? Yeah. He seems like one of those people that freeloads off the talent of actual musicians and follows them around trying to be centre of attention.
I also didn't like Courtney from the Dandies. He seemed more full of himself than Anton, but in a more vain, 'look-at-my-pretty-face' way.
