Star Trek is and was a format for storytelling on tv.. And too many of the movies have been the not-too-compelling-anymore story, "Defeat the Bad Guy."
yes...Season Three of TOS and Seasons 1-2 of TNG, some of Voyager and most if not all of Enterprise demonstrate just how good TV TREK can really be...
TOS movies were good, and in Khan's case, GREAT. PHASE TWO, based on what photos I have seen, would have come out about as silly as BUCK ROGERS did. Some of the so called 'script treatments' would have made THE NAKED NOW look like Citizen kane. Not doing Phase two, with GR running it, was what saved TREK; IMO
