This is the part that worries me the most. The theatrical cuts of all the movies are fine except for Star Trek: The Motion Picture. When the movie was originally released, it was basically unfinished. A few years ago before his death, the director (Robert Wise) went back (with some help) and finished the movie by adding special effects and trimming some scenes. The director's cut is absolutely wonderful compared to the theatrical cut. Personally I think the theatrical cut should be thrown in the garbage. I will be buying the movie pack but won't watch ST:TMP. I will stick with the regular DVD on that one.
