Forget “CGI/mo-cap is the devil” versus “CGI/mo-cap is the future”. Either way you don’t get a human, clumsy moment like that little trip/kick without live actors. Or without them putting in three days of exhausting-to-the-point-of-sloppy stunt fighting just to get that overall hallway sequence right.
Anyway I’d never seen Oldboy till the amazing Dave got us watching it this weekend, and the storytelling’s even cleverer than the fighting. Most grounded psychotic movie I’ve ever seen.
