Of course the number one most memorable thing about The Motion Picture is the visual effects. The movie manages to show (for long sequences of time) how good the film looks with its budget and it is just incredible to watch. It also helps with the soundtrack being as good as it is. However, although the film has a beautiful look and a great soundtrack, the essential film itself does tend to drag. There are long (and I mean long) periods of time where nothing is happening. It seems like the director and writer were going for a different feel then the normal Star Trek feel. So overall while it does drag, Star Trek The Motion Picture still has some enjoyment to it.
