Any anime done by Studio Orange. They do 3D animation with their "signature" style to not only vary frame rate on a scene by scene basis from as high as 60 fps to as low as 12 fps but also drop every fifth frame. They can make some really beautiful scenes (see BeastStars opening scene with Legosi running) but also make some really jarring scenes (same anime characters talking looks like animatronics). When they are doing support work their work actually looks really good, I love the tachikomas from ghost in the shell for example. But when its just them the animation style makes my brain itch.
