Media criticism has been around for a long time, but with the decentralisation of the tools to create and distribute media it's become increasingly easy for media criticism to be as simple and attention grabbing as possible.
A huge part of this simplification has come from revenue models based entirely on drawing the largest possible audience to sell advertising space. The larger the views, the greater the ability to sell more important advertisements.
This is made more complex by the blending of entertainment and criticsm, where audiences are free to develop parasocial relationships with creators. Ultimately, this creates a paradox: creators need income to keep making content, so they use their social capital to advertise products or services. The more clicks, the more money. So it's beneficial to avoid nuance, to create the loudest, biggest splash you can, every time.
Reliance on spectacle.
