Simply rating 5 doesn't tell me why you rated so high.
I won't lie, I don't like seeing the 4.5s but I would rather that with a reason than top marks with no cohesion.
We are here to write, so why not scribble a dribble of thoughts below, instead of avoiding a post and pretending to think that a rate is better than a well worded annotate.
The space is there for a reason, to help not hinder.
And a four won't break down your metaphorical authors door. That is eighty percent, four fifths right for your content.
Not everything is perfect, so don't lurk if an average rating is waiting for you, don't feel hurt, it could be considerably worse.
