I'd just consider theme when deciding the Overall score, and consider knocking a star off if it misses it by a long way.
I feel that the theme is given more to inspire and provide impetus, rather than be a straight-jacket around one's creativity. I don't think it's important enough to be rated.
Ah, but don't you think these two points are kind of contrary?
By keeping 'theme' a separate item, it can be graded separately from the rest of the game.
If the majority of people feel the same way about theme but theme doesn't exist as a separate item, you might find people docking points off the overall whereas
with theme as a separate item a game with poor theme can simply be given a poor theme score and the overall can continue to function as the general pleasantness that the game delivers.
I don't really like the term "enjoyment" as it's too close to "fun" but exactly as intangible. It also doesn't really bring to mind "humor" (not that I think that's a broad enough category?).
Some suggestions as replacements for one or both: Charm or Emotion. Kind of vague on their own, though.
