I watched it, to be honest I think it would've been considerably better without Chris Evans and just Matt LeBlanc and perhaps Chris Harris or the guy who won the competition leading things. Matt's Nomand review was great, and his laidback vibe helped the other challenges. The Landy/Willys challenge just showed Chris to be a petulant child who couldn't bear to lose.
I just don't think Chris' TFI type style is right for the show.
Sabine was a bit underused - probably due to her language(!) - and a shame not to see more of the other presenters in episode 1.
Episode 2 will be interesting but I doubt I'll last the rest of the series if Chris doesn't calm down.
