Low gravity movement is not what you see in the movies. The movies simulate 
low gravity with slow motion, but real low gravity does not actually impose 
a slowing of motion. All the fast reflexes evolved for our 1 gravity world 
are still in place on the 1/6th gravity moon, plus everything weighs less 
yet the mass is the same.

So what you end up with is motion that looks weird and fake because 
absolutely NOTHING prepares us for what low-G motion actually looks like.
