I like where Glaiel was going with this, but I think the categories would still need work. Here's my take:
GAMES:
>Graphics
>Audio
>Gameplay/Controls
Originality
Overall
MOVIES:
Graphics
>Audio
Entertainment
Originality
Overall
As a content contributor, I feel like the categories are important for knowing what people liked about what I create. Some people are more able to put what they feel as a number than to put it to words.
The scores also need a change. Keep the 0-10, but add a "-" before the 0 so that if the reviewer doesn't want to score certain areas, they don't have to. Even in the "Overall" box - some people just want to give a person an honest critique without helping or hindering the review score and maintain neutrality. The benefit of the "-" will also help out when changed to the new system. The pre-existing reviews will have that set as the default in the new categories.
