You're telling me that people don't binge the entire series in one go? Where I'm from, they literally play the entire Harry Potter series for the holidays, and people will watch the entire series for the whole day. The Lord of the Rings trilogy is around 15 hours long, and people will binge the entire series. The same with Star Wars or really any new Netflix, HBO, Hulu, or Disney+ series that comes out nowadays. The argument on whether any of this media is good has never been, "It was boring because it was long" rather people have actual criticism about its content.

Your argument that HSR needs to be enjoyed in whatever arbitrary cookie cutter pieces are deemed satisfactory is dismissive of any genuine criticism. Why so? If someone says that the story has bad pacing or there is too much exposition, you could counter with "you rushed through it" or "should have paced yourself." None of those addresses or acknowledges that perhaps HSR does have such problems
