Can't really say much without reading your novel and knowing the full context of their comments, but the comments doesn't seem all that bad tbh. They aren't hurling insults, just expressing frustration. And i will tell you a secret, people who show frustration actually care about your story. Those who don't care just leave without bothering to waste any more time. These people don't even say they are leaving, just that they don't like something, and that they would rather skip it. Again, i can't say much as i don't know the context, but there will always be people who won't like certain aspects of the story, so take it as you will, but it's not all that negative. So long as what they are saying is logical within the context of the novel, i would say it's all fine.
And honestly, i would say negative comments like these are actually better than the low effort alternatives. Like for example i see some authors on Royalroad mass +reputation star low effort comments as 'Tyftc!', and then ignoring all the long criticisms. Makes me wonder, is that what authors really want? The kind of low effort readers that spams 'Tyftc!' in every chapter, which seems so useless to me in the long run, as if having bots instead of actual readers. Sure, i guess it can make the author happy, but i can never bring myself to be that kind of reader tbh.
