I liked the first episode, too. Regarding tweetgate, I think they should let the girls keep going. Lots of "acts of God" happen along the way of the races, and this just happened to be some good luck coming their way IMO.
I much prefer the double elimination on the second leg to the cruelty of eliminating a team on the first leg, or even before the first leg.
The team that lost were amusing, they were so laid back. As we've seen before, too much education can be just as unhelpful as not enough.
I love seeing Ethan running the race. I always liked him on Survivor. But it's too early to have a favorite team.
