Well “plot holes” are his words not mine, and he is mostly talking about artistic license. Also a lot of discussions about plot holes these days revolve around the “logic” of a film.
EDIT;
from wikipedia - "In fiction, a plot hole or plothole is a logical inconsistency within a story. Such inconsistencies include such things as illogical or impossible events, and statements or events that contradict earlier events in the storyline."
Actually I’d say he’s using the term correctly when also including the term “artistic license.”
