I personally dont think Chris Works on TV. He's tried it before and bummed, so I'm not sure when he's going for it again. I hope it was just first show nerves, but some of the time Chris' lines seemed a bit contrived.
Also I dont think the format of the show is working well either - having the guests behind some giant TV screen that Chris can turn on and off at will was just wierd and often made Chris look arrogant (I'VE heard enough from you so I'M turning you off...) - why not get them on the stage and involved in the action? I also think that the Sharon Osbourne pre-recorded questions just made the show look cheap and made Chris look like he was trying a little to hard to show off his famous friends.
I have a feeling the show will get worse once Chris has used up is industry friends / regular Radio 1 guests (Davina McCall, Justin Lee Collins / Jimmy Carr.. and maybe a couple from the mountain climb).
I love Chris (and the team) on the breakfast show, but don't think he's got what's needed for a careen on the screen.
