Most of the points express a disappointment with mainstream Hollywood movies, which if you don't broaden your horizons is eventually going to lead to disappointment for any cinephile.
"The sitcom-and-laugh-track era appears to be over, thank heavens" I would agree about the laugh-track era being over - but thats hardly a new development. I've been watching the Larry Sanders show from the early 90s which was a landmark show without a laughter track. But to say the era of the sitcom is over is nonsense? There are so many great recent ones.
The one thing I agree with is that scrolling through Amazon Prime / Netflix is a draining & dissatisfying experience
Otherwise, I don't know... I've been watching movies at varying frequencies for decades and I certainly don't feel I've come close to even really tapping the surface, don't feel like I can guess immediately where the director will take me & don't feel really constrained by Vonnegut's theory about there only being six types of story.
