I dare say we've already established that the six original Star Trek films couldn't have left any real cinematic mark, since there's very little that's actually "cinematic" about them in the first place, except in the most superficial sense of the term. They're all shot on film and shown in cinemas, yes, but is there anything aesthetically cinematic about their style, their cinematography, their approach to this material? If anything, these films helped to bring indifferent television aesthetics to the big screen, treating film and TV as interchangeable media. These films are ultimately little more than really long TV shows; sometimes enjoyable, sometimes not, but rarely all that interesting as films.
A surprisingly engrossing discussion of the first six Star Trek films by Jason Bellamy and Ed Howard. I only stumbled upon this discussion because it was linked at this site, which I discovered while searching for information about B-movie producer Burt Topper.
