I didn't really feel that too much...with the exception of the final scene where the Predator guards are doing their Raiders bit and the camera angle is up high and behind them. I honestly thought they were doing some sort of funky dance moves. It was very bizarre.
Yeah that part was really bad. Like they've got gout.
It came across like rendering stutter to me, maybe a budget problem and unable to redo? It only seemed to happen noticeably at a handful of points.
To me it looked "wrong" from the offset, it really felt to me like there was almost no motion blur and movements that should have been a bit distorted due to blur looked very sharp. Just odd to watch.
