And making movies like that was literally killing the franchise.
I gotta disagree man; I think this is a common misconception.
The first Star Trek movie was a financial success, but Paramount didn't meet their expected margins. TWOK was a better film, done on better margins, with tighter studio controls and by a more seasoned team. But both movies were successful, and obviously TWOK was the better film overall in almost all respects.
ST3 was also a commercial success, again done on a smaller budget. The studio just fucked up hiring Nimoy to direct, and Roddenberry knew this. But again, these movies weren't killing the franchise, they were all financial successes done on relatively low budgets compared to the original.
Star Trek: A Voyage Home was one of the most successful movies to date to come out of Paramount when it was released. People loved and still love that movie; even though I personally fucking hate it (it's my least favorite of them all, outside of the reboots).
So I can't say that these movies were killing the franchise. Star Trek was a Paramount cash cow, and people loved ST4. Final Frontier was ass, but Undiscovered Country was actually a pretty damn good ST movie; it's definitely better than the reboot films.
The only reason they stopped making these films was because the cast was too old, and there were numerous compelling reasons to try and move on to making a TNG movie.
JJ made Star Trek movies watchable again.
I'm not sure how? I mean, are you a Star Trek fan, or..?
Lucas was doing the same thing to Star Wars, and luckily, JJ is there to save that franchise as well.
JJ isn't saving anything. We haven't even seen the fucking movie yet man, c'mon..
IMO, Just about any director could make a competent Star Wars film. Just not George Lucas, because he's not a very good director.
