I don't think he is, but it's difficult to avoid a direct comparison when the format is so similar (a bloke talking to camera in front of a live audience in an aircraft hanger). Clarkson was a motoring journalist before getting the TG gig, whereas Evans and LeBlanc are true enthusiasts i.e. cars are a hobby/passion rather than a job. I think that will inevitably alter the 'vibe' of the show.
By tomorrow (Wednesday) I believe Sunday's opener will have aired in 183 different countries around the globe.
Well, this fan enjoyed it.
