1) No chemistry between the hosts, they shoot off clearly scripted one-liners and then stand there waiting for the others to react. The writing is awful, but so are the hosts. It's like a bad comedy troupe. COMPLETE lack of confidence and natural poise.
2) The Lamborghini segment was the best one out of the three and the hosts barely did ANY talking, just rehashing the same statistics and facts over and over and over and over and over again. Their "research" must have consisted of reading the sales brochure for the car, because they didn't seem to know anything. I hate to draw comparisons to Top Gear UK, but the hosts definitely know what they're talking about - they can rattle off makes, models, engines, and other random facts, all of which enhances the commentary.
3) The "track" is covered with what appears to be trash and/or garbage (a bale of hay and cones, what the hell?).
4) Commentary (or the lack thereof) sucks, especially coming from the one with glasses and the beard. I find him incredibly annoying and don't really see how the other two hosts besides Carolla add anything to the show except take up space and make me want to hit something.
5) Production values (camera angles, shots, etc.) are ehh. Clearly the editing and camera work is NOT up to the original.
6) I saw a preview of one of the upcoming segments a few months ago and was equally uninspired.
I'll give it a few more episodes to see how it develops but this one is a sure-fire flop out of the gate. I'm not surprised, frankly.
