That's a good point. I would gladly revise a review on an incomplete story. There are a few that come to mind already.I have a question for the regular reviewers. When you read and reveiw, do you go back to your reviews after updates?
I always try to give a fair assessment of a story, but I prefer to give an instinctive mark for how much I enjoyed the story, rather than making an academic judgement.
Sometimes, I feel guilty that I haven't graded a story as high as the author would hope for, particularly where mine is the only review for the story. But it's the responsibility of other readers to register their viewpoints also.
A story's worth can not and should not be measured by only one person's opinion.
