Now that we've got a better idea of the concept...
As a preface, I've said it before and I'll say it again, when it comes to monsters I lean towards the beastly/animal/creature side of things. A post-apocalyptic zoo is absolutely up my alley, but the choice of it being cannibals instead of hybrids/mutant animals is personally disappointing in that regard.
For me, this house is gonna' be riding on how the cannibals look. If they're all geared up to look more beastly than human, I'll happily take that! If not, then this concept is "Close, but no Cigar...", a literal imitation of what the concept could've been.
I do have faith the team can pull it off, but in terms of anticipation it will be on the lower side as the monster choice is not one that excites me.
