Well---no film is perfect----but if there had been no Star Trek The Motion Picture-----then there would have been no ST movie franchise ------ Period.

And if I am not mistaken----after it is adjusted for inflation---ST:TMP had been the highest grossing ST movie(yes---even more than the beloved Wrath Of Khan!)----until the 2009 release of Abrams's new ST film.

I do agree with your points that you made above------- having said that there is a certain amount of subjectivity when it comes to this kind of analysis.

I personally felt that the CGI version of the Vger spaceship looked exactly that----CGI!

I also think that the CGI depiction of the Vulcan planetscape also looked out of place for a movie made in 1979.

I thought TMP (Director's Cut) was OK. It had the best soundtrack of the six, IMHO. I also liked that "Kirk's shuttle ride to the Enterprise" scene that everyone seems to hate.

I think we can tell those scenes were CGI, but I doubt the average person can. Some of those vintage effects like the warping and the transporter beams kind of look like CGI even though they weren't.
