What was the studio�s attitude towards Star Trek in terms of movies?
After the original motion picture, the attitude was, "We have something we can make a lot of money off here, but we need to shift it away from Gene Roddenberry�s focus on the concept of Humanity, and turn it into a bit more of an action film." That�s certainly what they did with The Wrath of Khan, and they�ve done it with the follow-up films.
For Gene Roddenberry, Star Trek was not about space battles, it was not about petty conflicts between human beings. Humans had evolved beyond that. This was always a point of conflict for the series itself because many writers absolutely hated being a part of the Star Trek series, because it�s very difficult to write scripts where you had no conflict between the main characters.
So space battles became a part of Star Trek in a much more grandiose way than they had been years earlier, even on the original series. Star Trek changed from that point on. Even to this day you may get episodes of Voyager where there are various high minded concepts going on, but there�s always a red alert, there�s always going to be some sort of point of conflict between the starship and another opposing side.
