It's interesting, and different. I like it!
It covers my basic thought process when buying a game:
Essential: Buy it even if I don't like the genre or concept.
Recommended: Buy it if I do like the genre or concept.
No Recommendation: Actually read the review to find out if I can deal with the flaws. Which is what I would do anyway if I heard that a game was a mixed bag.
This seems A-OK to me.
