Sometimes you can tell you won't enjoy a story early. For example, I read the rewrite of "I Built a 'Stress Relief' Artifact to Pay Rent; Now the Silver-Rank Guildmaster Won't Leave Me Alone," and I knew I'd dislike it from chapter 4. Because I am often prone to "sunken cost fallacy," I kept wasting my time reading it all the way until chapter 16 (and didn't enjoy any of it).
Fortunately, ratings and reviews are just opinions; just because I didn't like the "stress relief artifact" story doesn't mean everyone will dislike it. Keep writing your story, and it'll find fans.
If it's not for me in the first chapter, I don't rate it. But I generally give 5 stars or no rating. I don't like the style of bullying authors by opening the first chapter for a glance to find an excuse to bash their rating.
@JayMark bad ratings aren't readers bullying authors; they're readers interacting with other readers. If reader A went "1 star because I hate overpowered MC" and reader B loved OP MC, then reader B is more likely to read a story despite the negative review.
It's better to establish a following elsewhere before taking on RR. The readers there think ratings reflect quality reality and the established writers have a hard-on to destroy the ratings of any competition they are able to. I wish bad ratings didn't deter readers, but they do very much.
