These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ninja Warrior
Ensemble Darkhorse: Minoru Kuramochi, a.k.a "Mr. Octopus." He has been ranked at number 4 on G4's craziest contestant poll and the number 4 reason to worship Ninja Warrior.
Scrappy Mechanic: The Backstream in Stage 2 isn't very popular with competitors or viewers due to it being a swimming obstacle, which is the opposite of the main goal of the course, which is not falling into the water. Heck, it's hated so much, it completely KILLED Sasuke 29's ratings.
That One Level: The Cliffhanger, on stage 3, where you have to move laterally while hanging on to a ledge about one knuckle deep, has ruined the runs of many all-stars, until they started figuring out that you need to swing like a pendulum, and only move your hands when you're at the right peak when your weight is at its lowest.
The Woobie: Katsumi Yamada's legacy of failure and the consequences in his personal life.
Kazuhiko Akiyama as well. After his victory, his health worsened and his sight started to fade. The announcers always let us know about this fact.
