When I showed someone a clip of the Battle of Hoth from ESB:R, he asked, “Why cover up the beautiful stop-motion? There’s beauty in that handmade craftsmanship and work. Why conceal it?”
That makes no sense, its still the same effects
The AT-ATs were given a bit of motion blur so that they could have more “realistic” movements, concealing the jerkiness of the original stop-motion.
