I can see where you are coming from with that comparison but Get Out worked better for me as a satire rather than actual horror something along the lines of Cabin in the Woods, i too thought The Skeleton Key was superior.

If the supernatural element is used wisely and in moderation a horror flick that capitalizes on that can be super effective for me (i.e. The Skeleton Key). You should definitely rewatch, it was actually a 2nd rewatch for me across a decade span and it was as engaging and interesting as the first view.
