I really love the closeups in TOS where they zoom into a characters eyes, dim the scene, but shine a light on their eyes. It's a really effective tool to both build tension and get into the head of whoever they're doing this so we can see their emotions/how they're processing whatever moment is happening. The eyes are the window to the soul and what not. It must have fallen out of fashion as being hokey and too blunt, but I adore it. I'd really love if that would happen more these days.I really wish those would come back in style.
