If it'll make anyone feel any better, I actually really appreciated those two columns on Shadow of Mordor. Seeing all the praise it got 'round these parts was encouraging, but without constructive criticism present some might buy the game and then feel underwhelmed due to all the hype.
Constructive criticism, I feel, is at the heart of the issue discussed in this column. Without it no artistic medium would ever move forward. Any budding writer/photographer/game dev/whatever can tell you that feedback like "yeah, it's quite nice" or "I really like it!", while encouraging, is ultimately useless in the grand schemes of things. I would even dare call it more useless than the rude and generally uncalled for "this is utter shit!" from the common internet stranger. Nondescript praise uplifts the spirit, but offer no grounds for improvement, while vague criticism is still at least an incentive to get better.
One problem is that a lot of people don't know how to provide constructive criticism. You like it? Ok, why? Did you like the composition? The story, the characters, the language used etc.? You didn't like it? Ok, while that makes me somewhat sad, can you tell me what I did wrong? Was it the composition? The story, the characters, the language used etc.? Or did it just make you feel something you didn't like? Did it disgust you? In what way? Because it might have been my intent to evoke disgust, but just in one particular way.
The other side of the problem is that a lot of people also don't know how to take criticism, constructive or not. Creators can't help creating a bond to their creation and any criticism hurts, but to improve, we have to move past this hurt and look for the reason and the logic behind the criticism. No one is immune from criticism, not even G.R.R. Martin, J.K. Rowling or even J.R.R. Tolkien. There is always something that can be improved and I consider it a creator's moral imperative to strive for improvement. Then again there will always be someone who will dislike your work, even if it's nigh perfect, simply because it doesn't suit a particular taste. One can't please everyone.
