*..products are full of these kinds of trade-offs.0..

*Exactly! 

I don't mind reviews which point out a tradeoff. But the review shoud be on the whole product not one thing/tradoff that the reviewer doesn't like.

*but if you say anything other than it's wonderful or deserves 5 stars you are considered a jerk

Personally I don't mind a middling review if ir's fair, accurate and honest.
For example they raise a technical fact such as the doors don't open.

Not reading instructions is common, but we're all guilty of that one :) 

But where Mr Slighty Grumpy comes out is when the reviwer leaves a poor review. Usually because they don't like the way you did something. Thats unfair as everyone does things differently and often there is no defined standard of  doing something.  

However Mr P*ssed Right Off arrives is when the reviewer attacks the product or the artist for no valid reason. Those shoud be deleted  as they serve no other purpose than to try to derail a product.

Pinky - you left the lens cap of your mind on again.
