Agree with you mostly on this, however I found the finale to be uninspiring and pretty boring to be honest. Definitely a fair share of luck required, and next to no skill.
Also, I just don't understand the tactics used by one of the final 3 once the first person had chosen their shape. I'm not sure why they volunteered to go first as it basically gave them a 50/50 chance of getting eliminated. If they had chosen 2nd, they would have pretty much been guaranteed a spot in the final 2 (given that the other person could have either picked the red shape and got eliminated or picked the green and chosen the other individual for the final spot). Seemed a very odd tactic, which ultimately backfired.
