Speaking of artifacts in motion pictures that we have all come to accept over the years, what about wagon-wheeling? I truly am surprised that with all of the technology out there, films still allow that to happen and that audiences still accept it. For me, it immediately pulls me out of the film.
Are you talking about the phenomenon where wheels appear to be rotating backwards? That has never bothered me, since it also occurs in "real life", for instance when looking at adjacent vehicles on the freeway.
