The first 4 legs were great, IMHO.
I especially like the "Who has keener eyes" roadblock in Chile.
Leg 4 was one of the best episodes of TAR. Not tasks-wise (the detour was so stupid. They could just ask for direction instead of using the compass. It was really stupid) but the things that happened. There was drama, tension, TAR reminiscence (the roadblock) and of course, the ending was really satisfying.
Another thing that I hated on that leg was when Rob misspelled Philippines. image
And after that 4 legs, teams began to be day/s behind each other and TAR did some ridiculous excuses like the bus and the "a storm is coming".
