After some more looks at all of the pics I've figured that it's not really the size of the head (because it really doesn't look all that small without the hat)... it's the damned HAT! They really should have done 2 heads, one with the hat and one without. It's clear that they couldn't properly engineer a hat in production that would fit over the head and not look too big. Medicom also had this issue.
That said, it's clear that there was some warping in the sculpt during the production process. That's a shame.
It's still not a total disaster, though. But at that price... damn. SMH
