I think I see where you are going with this. I too was thinking the composed humans couldn't show their true emotions since they were enslaved and controlled.

I believe 343i can fix them up enough to make them more interesting by adding more menacing animations. I find the back plate fluttering to be quite good and scary. Knights walk a bit stiff legged so maybe that can be improved to be more fluid.

The Watchers are nearly perfect in my opinion, as are the Crawlers. Perhaps the Crawlers animations could be made even more dog-like while adding a bit of gravity to their jumps.
