A great and exciting show. I saw 2 competitions I got the impression that the host wanted the weaker of the teams that made it to the finals in the 2 competitions to win and that is exactly what happened.
To make the selection of the final winner more credible, transparent and unbias, I suggest the host should not judge any of the challenges in the finals. Judges for the challenges should be completely neutral, new and randomly selected not part of any of the previous episodes
