When he said "yellow is the colour of sickness" I thought "what? No! GREEN is the colour of sickness. And Yet they picked it for the hero! Yellow is the colour of the sand and the Sun. Obviously it's a good colour!"
I think the conclusion of the video is:
- yellow makes more sense as a weakness because it stays on theme (green vs yellow, they're both colours).
- wood would be a less problematic weakness to work around (okay, the flamethrower thing wasn't so great, but he could have an axe instead, plus it's easier to find one. Wood's not such a solid material, you can break it relatively easily).
It's an interesting concept at any rate, I'll probably watch it again, although maybe not every week.
