Soldato
Really the only people who carry the new show are MLB and Harris. Sabine is a bit of a forced character in the studio, Eddie is a bit of a blank wall.. It should really be like this, put Matt with a suitable sidekick host, and let Harris do all the cool video segments in his style. That would be almost perfect.
On another note, if we are talking about binning all the hosts and re-re-starting fresh, then this chat came up elsewhere today and I think it would be fantastic. Hugh Laurie, Rowan Atkinson and Stephen Fry. They are all petrol/gadget heads and they are all friends who have that banter going between them. Plus, everybody loves them.
The problem with that is they're all equal superstars.
With Clarkson and Co, Clarkson was clearly the real star and the other two pretty much sidekicks who became famous just for that show. I can't see Stephen Fry and Hugh Laurie being sidekicks to Rowan Atkinson. Perhaps in the Black Adder days, but not now.
