I liked this show a lot. I managed to watch it all in 2 days. However, I found it spent a lot of time focusing on certain teams and being repetitive with their back stories. I also would LOVE to see the final board with all the teams who completed it and their times. Some episodes you would see so much of a certain team and no idea if they actually ended up completing it. Overall it was a great show but maybe 66 teams is too many, since we aren't able to see them all.
