I think that in general, there are about 3 universal qualifiers that can be used to identify whether or not a game has good writing, with the rest being completely subjective.
1. The writing must lack plot-holes. The more of these, I think it's safe to say the more objectively worse the writing is, because regardless of the content, if there are plot-holes, then it just means they are failing to rectify their mistakes.
(two and three kind of go together)
2. The writing must identify a target audience. You can't write to everyone, and expect every person to relate and understand/enjoy what you are writing. You need to identify your target audience, for example, targeting people who enjoyed aspect x of movie Z, versus people who enjoy aspect y of the same movie, and making sure that you understand what kind of emotional response aspect x invoked in said audience.
3. Writing your story so that all the elements are composed to evoke aforementioned feeling x to the target audience. Basically, I'd still call a story badly written if the story is written so vaguely that the target audience doesn't particularly enjoy it, while people who don't enjoy element x at all end up enjoying it because there were too many unintentional inclusions of elements y or z.
For me, this is how far I feel the objectivity of qualifying writing as good or bad goes. And someone who cannot comprehend what the writing conveys has no business reviewing said piece, because they won't understand it on a fundamental level, well unless they are reviewing it specifically for their peers who share the same views as they do, but it wouldn't work as a general review.
