Negative Reviews

Made the mistake and checked out my negative reviews on Amazon and Goodreads. I wouldn't suggest doing this. Thankfully, there are only two. The one on Amazon said, "Writes at a fifth grade level. Lacks understanding of basic physics."

Wow!

Most of my reviews are positive, thank God! So the "fifth grade level" comment hurt at first. But it soon washed off me a bit with the second half: "Lacks understanding of basic physics." My story is sci-fi, but it's not hard sci-fi. I don't get too deep into the science because it skews space opera and there isn't a ton of physics in it. So no idea what they were talking about. They, of course, left no example for me to go on. I wonder if they meant I defied some law of physics. I try to adhere to it as best I can, usually. None of my beta readers pointed out any issues concerning physics.

As far as this Amazon reviewer goes, I think they were trolling because they were not a "verified purchaser" so screw them.

My negative Goodreads review was really weird. I received two stars, but no written review. I decided to check the reviewer's reading history. It was pretty extensive. But 90% of the books she read were historical fiction. And the other 9.9% were contemporary mysteries. My book was the only sci-fi on this person's list. Everything else got 4 or 5 stars. Meanwhile, the one science fiction she reads she gives it 2? Is this a thing? Are they a troll? So confused.

Does anyone find these instances weird? Has anyone else found situations like this in your reviews? Or do you avoid your reviews all together?
