You know I have to say, when this show first came out it was horrible because they tried too hard to copy the BBC version (which I *love* and watch fanatically). The show and the hosts were trying to be something they were not, and it showed. They were trying to do all of the segments (news, hot lap with Stig, SIARPC, car review, challenges, etc) and it seemed so forced and artificial.
Now however, with the exception of the SIARPC and hot lap with Stig, they've gone to the full-show serial competition where the three of them are involved in one adventure for the entire show. MUCH better, and different enough where they can stand on their own. I think each host has finally settled into being themselves which is a good thing. Now, the SIARPC and the Stig laps seem even more out of place though. Get rid of those two segments and just make it a full hour three-way challenge/adventure and I think the show could make it. I know I'm still watching.
