While I will agree that the film could be considered "slow" at times, I would say that Star Trek: The Motion Picture is a criminally underrated film. It provides an intriguing story alongside many incredible visuals (including close-ups of our precious starship, the Enterprise), as well as a gorgeous musical score. Granted, this is not a perfect movie, but if you're looking for something outside of the space warfare styled adventures that some films such as Star Wars have, and if you don't mind the long showings of the visuals within this movie, then I suggest giving it a shot.
