That's a healthier attitude than many carry into their reviews, IMO, who slap on 0 if they're mildly irritated or disappointed, but then, the latter attitude isn't any less healthy than the opinion that scoring a game a 0 (a subjective value) is "trolling, plain and simple."
The larger truth at play, in these review wars, which is observable, is the recent politicization in the past several years of the "Critic" scoring review, with a deeply corporate liberal tilt. But that isn't the primary concern, here.
No, far more problematically and stark, for both user and critic scores, for TV, movies, and games, is a trend that has becoming increasingly entrenched over the past decade, and that's runaway scoring inflation. It's unchecked and undeniable. Ergo, to any observers concerned over manipulative sabotage, the greater concern, undeniably, isn't negging, or "review bombing"....it's corporate manipulation to positively distort feedback for (usually) their most costly projects. This is the major problem in the online culture of review aggregation.
You're being bamboozled into focusing on the wrong thing. They've got you pretzeled up telescoping on an insignificant issue while they dig their tentacles in, bury them deep, and take control of something which was never intended to be under their control.
