STIV: I actually also remember fans happy with this one
Despite the huge popularity of this movie, this was the one that caused a mass exodous of jaded, angry, older TOS fans from our club. They saw it as "the dumbing down of Star Trek" and were insulted by it. Then along came TNG - and they reckoned it vindicated their choice to jump ship.
I'm not saying they were right, but it happened.
