Uncanny valley. Tag -> pool?

Regarding the tag uncanny valley.

This is an inherently subjective tag. Different people get uncanny valley style reactions to different things. Personally I don't get it from at least half the images that are tagged as such, but someone else obviously did so I feel it would be wrong to remove it.

From the howto:tag wiki:

Do not use subjective tags (such as sexy, cute, hot, etc). These tags are problematic because they are based on personal opinion, and different opinions can conflict. Images based on a subjective theme can be collected into a pool instead.

I would thus propose that uncanny valley falls into this category and thus that the tag should be removed and replaced with a pool.

Thoughts?

Definitely more suited for a pool.

Pool, no doubt. Still, even if I personally don't see that quality in all those posts, but for some of them, to quote Wellington, I don't know what effect they will have on the enemy, but by God, they terrify me.
