“Detective Knight: Independence” (** out of four) was a tepid third entry about title Detective Knight (Bruce Willis) who is assigned to stop a former EMS worker (Jack Kilmer) who has become unhinged and a deadly threat to the city. Final entry in this series is more-or-less on par with the first two; not bad but derived from too many other Willis cop movies, “Heat” (which starred Kilmer’s dad Val), and in one key scene “The Dark Knight Rises.” Willis’ real-life health problems are all-too-evident as he’s hardly in much of the movie and most of his dialogue seems dubbed. Lochlyn Munro once again adds some punch as a hard-nosed cop.
