I can tell you where it happened for me. That rolling ball of brontasauri, or whatever they're called now that bronto has been ditched (also there'r FOUR food groups), in King Kong. I'm all for good CGI, but bad or unnecessary CGI is just the worst. Rehire all your effects guys and model makers and give them explosives to play with rather than fake blowing up fake stuff. It should be fine for lightsabers and blaster effects though.
