The "Looks OK" option on Low Quality Post reviews is not ideally worded.
Due to the fact the post has been reported for Low Quality means in most cases "something" is wrong with it. Even if deletion or editing is not the solution, it shouldn't be concluded as "Looks OK".
Change "Looks OK" to something which more accurately represents the outcome being used for the review.
"Deletion Not Required"
Then our choice is what the review outcome actually is - "I don't think this should be deleted" rather than "this looks ok to me".
If people have to choose "Looks OK" for what is a terrible post but doesn't need deleting, they might be forced towards a general "meh" attitude "Doesn't look OK but whatever".
Whereas, their choosing "Don't Delete" might push "No, this does not need deleting, but I'm going to damn well downvote and/or comment after this review" *

Suggested Edits don't have "Looks OK", they have "Approve", and the Low Quality review choices should be allowed the same logic and sanity :)
