Would it be more polite to say that Tarantino is inspired by other films or that he makes homages to other films and film movements within his own movies?
Maybe, but even Tarantino himself says that he steals content from other films. His works are, in addition to his own original ideas, pastiches of other movies.
There is at least one error in this otherwise excellent exploratory Insider video: Reservoir Dogs came out in 1992, not 1997.
