I loved the original TG and I watched this last night and I thought it was ok.
The segments in the tent just didn't seem as polished as when in the studio on TG and it did sort of feel like they were being held back, I cannot put my finger on it, it was the same as TG but different, something was missing, maybe it was just the atmosphere in the tent maybe.
The outside sections were as good as they used to be that said, the La Ferrari, 918 and P1 test has been done and better by
Chris Harris imo, it was just too late for Jezza, Hammond and May to have done, Chris Harris did it nearly a year ago and from what I remember there was the Chris Harris team, Jezza, Hammond & May, and another team there all filming the same day/days.
I think the 'tent' segments will get better as the trio get more used to them.
