Exclusively positive opinion is boring

The idea came when going through youtube. I see a lot of 5-6 years old channels posting essentially the exact same material each week. And the comments are always the same ("good work", "you're awesome", "loved it"). Though they might be more elaborate in the way they formulate their thoughts, it always boils down to this overly simple exclusively positive idea. and it's BORING !

I find it completely mind numbing, debilitating. It does not propose any form of improvement, yet I highly doubt anything can be so perfect. And it pushes creators to only use the same formula to make content, all they videos start to looks the same. We have to give constructive negative opinion to create the momentum needed for improvement and keep things alive.
