I agree, the leg design was really bad. Let's break it down.
White pearl: An okay task, but only because all three teams started at the same time.
Rappelling: What basically killed all tasks that followed. It spread the teams too far apart. Starting here, you won't see two teams in the same frame. And the puzzle part of the task is just pathetic. They could have at least broken the frame into puzzle pieces to make the task harder.
Alibata memorization: A good task ruined by teams being too far apart.
Clueboxes on the beach: An okay task I guess. If the beach had more than 200 clue boxes, I would be satisfied. But the fake suspense just made it unbearable.
Just four tasks? I'm sad.
It sort of reminds me of the season 19 finale. Though happy for all three teams, just a let down of an episode.
