So this arc comes to a happy ending, it was an amazing hunt for the truth behind Old Man Genno's genius plan to have fun before he dies of old age. What a fun way to go out eh? So it was just a fun treasure hunt meant to take revenge on the Leaf for the death of his son, but when he met Naruto, it seems he changed his plans. The guy had almost everyone fooled except Shikamaru who himself was scratching his head at this. But luckily we have the Konoha 11, who used each of their abilities to figure out the puzzle behind the traps.
It seems the old man didn't want to really hurt anyone, but made it seem like he would and had all the cards to do so. Something like this would be an efficient way to do things. The animation for this episode and pretty much for the Arc was pretty good overall, this episode especially. Compared to other episodes in this season.
A treasure hunt like this, would be pretty fun actually. Find the traps, the truth and be able to disarm them, or fail and let the entire thing go up in flames. The risks are all so high that you have to work hard so you do not fail your village, people and yourself. So this would be worth playing for real.
