I liked some of the bits of new Top Gear. Chris Evans was almost offensive though, in the way he came over as fake and over the top. I think authenticity is what Top Gear needs most, and he had very little.
The idea of a head to head for the celebs is interesting, but you might as well go to the trouble of making it a Race of Champions style event - two laps didn't work out in original TG and they don't work out here. Also, the rallyX- aspect makes it even more weather dependant than the original, I rather liked the mostly level playing field that tarmac provided.
Eddie Jordan should probably also go. The remaining four make an interesting quartett of different characters, that are all believable.
