After watching the second episode, I think its fantastic. I've been a big Harris fanboi for a long time, so i'm glad to see him doing well in the role.
I like how they aren't going for constant comedy and hoping something sticks. Instead, they have a few very well timed and funny jokes.
The only thing that bothered me slightly was the snowy race. It was obviously edited for excitement, which is somewhat expected. A car would get stuck and somehow catch up. The weather changed from snowing hard to being clear. It went from day to dusk. The lambo bumper was crammed with snow, but clear at the end.
