I'm rating it a 7 out of 10.
The Mercedes / BMW / Cosworth challenge: kinda fell down near the end with the scoring, mainly because of the randomness of some of the numbers and the Colditz thing was just silly (were they allowed to shoot interiors of that hotel?). Good way to hint to people that there'll be outtakes on the website, though.
News: that went all right, a little too dwelling on the Range Rover. (Perhaps they should get Wayne Rooney as the SIARPC. Speaking of which . . . )
SIARPC: frankly I think that fell very, very flat. Partly because Jeremy doesn't talk politics very well, partly because Campbell really didn't seem to know how to answer in a way that would hold an audience. I'll bet money that when Season 15 comes out on DVD, they'll cut this segment.
The Isetta: they were a bit overlong on the joke of James not getting out. Might have worked better if we'd seen footage of James trying to climb out the sunroof.
The Porsche review: sorry, but for doing the lap you really needed the presenter out there defending his review. The review itself was pretty good, though.
So, to sum up: the end of the cheap car segment didn't really work, and the SIARPC really fell flat. I'm expecting they'll do better next time.
