I've had a few funny comments from people who explained - in detail - how they'd change my story (to the point that it was a totally different story). If you want to read a totally different story, maybe go read a totally different story, not mine.
I've also had someone say they didn't like the title of my story and therefore gave it a 1 star rating.
From the reader side of things, I remember one writer who wrote about a professor at a college who was purportedly very strict with her students. That writer wrote some 10 to 15 chapters (five to seven pages each), about how she came down hard on her male students blistering them eleven ways from Sunday and warning how she was going to met out the same to her female students. After ten or twelve chapters she finally gets around to dealing with a female lead character, and what happens? Limp-wristed the rest of the story. I gave 4 stars up to the disappointing chapter(s) then gave a 2 stars.
My point is, that sometimes it's the writer who imparts that they are going to write a different story, then falls short of their goal. Foreshadowing what they intend to do, but then take a different turn. If someone went to the time and effort of writing a detailed comment, I'd actually give the common-tater some credit for in-depth analysis of the story and see if their comment had any basis.
Then again, sometimes people just have a different vision of what a story is about. Creatively, I'd still take note of what they said, for future reference.
