YouTube comment sections are weirdly positive always. It could be a video of some horrible crime and the comments will be about how great the channel is and encouraging the channel to keep making more videos. When j visit actual fan pages anywhere else online there are always a mix of opinions. But youtube is constantly full of obsequious people
When I still used YouTube it recommended me crap I could hardly have cared less about or even things I actually disliked.
To me, Youtube was always synonymous for faulty algorithms.
