I missed that there was a thread for this. This has become my replacement for Amazing Race basically, and it feels like the first season of the show where everything was a bit looseygoosey.
I will say there are weird rules that they never explain though, like apparently they must do an activity at some point on a leg, that can sometimes make the team decisions a bit baffling. Same with apparently needing to work at least once per 'leg'.
There's also an Australia show called Rush that's similar but also different that could be worth watching. It bombed and died after 1 season, so there isn't much commitment.
