It is unfortunate, but nearly unavoidable, that what is innovative and successful will be copied until new viewers find the original unchallenging or even imitative of the successive work they have already viewed. Tarantino has been entirely forthright in acknowledging his debts to the innovators in this and other genres. The primary difference between the approaches of this film and Tarantino's "tributes" is that these intend very little irony or parody, while his work is hyper-aware of such things. I think it is important to view the Scorpion films in the proper context: They are excellently produced potboilers which are very pleasing, and their use of Meiko Kaji as an unapologetically aggressive and vengeful woman looking out for herself, while praiseworthy today, was particularly innovative 35 years ago.
