ELI5- why can movies make CGI human faces and movements that look 100% real and normal but video games always look fake even with large budgets?

A video goes at a minimum of 60 frames per second. This means that all the game’s code, all the graphics and everything else needs to be processed in at most 16 miliseconds. Anything less than 16 ms and the game seems slow or seems laggy. Obviously, 16 ms isn’t a lot of time, so often times you make a tradeoff between features (gameplay) and graphics.
With movies, each frame is played back at 60 frames per second, **but** each frame doesn’t need to be processed in that time. With movies, each frame can be rendered in as much time as the producers want. Which means that you can have stunning graphics simply because a single frame took maybe, idk , 30 minutes to render. Because movies are interactive, you can take as much time as you want to draw the frame, which allows you to have better graphics.
