With practical it is all in the way the design and animatronics interface with each other.
ADI's often only demonstrated the ability to do one or the other.
Fugitive's initial sculpt looks absolutely superb, and ADI's animatronics can certainly do a lot, but when they came together it looked awful.
Not much point in functionality if you warp the design in the process of giving it that functionality, in my opinion anyway, I'd rather have something more aesthetically pleasing that's more stiff as a viewer than the other way around although neither's obviously ideal.
