Trek Core means.
Doesn't mean these qualities are always good, it is e.g. unbearable to watch a movie like TMP.
Unbearable to people with short attention spans who need an explosion every 10 minutes to maintain interest.
Star trek, the motion picture is an amazing film with a fairly large following (see IMDB).
Just because those who liked this film do not chime in here, does not mean they don't exist.
And a lot of people hate st 2009. Again, look at reviews all over the internet, youtube videos and comments, to see that the number of people who hate this film is underreported.
