Batman & Robin (may it rest in peace) was a reboot of the Adam West style of Batman. They tried to reboot Hulk (it wasn't the bomb, it was his DAD1?1) but they discarded that idea to reboot the tv show Incredible Hulk, and Star Wars, not just 1-3 which doesn't really count as a reboot but all the old republic books and games, isn't going to stop 7, 8, and 9 from being made....When has a popular media franchise EVER gone back to a discarded continuity after rebooting itself? I mean, does anybody expect the Batman movies to go back to the Burton/Schumacher timeline now that Nolan's trilogy is over? Or maybe even back to the Adam West era?
That's not how it works.
And that argument that Nemesis killed prime trek is weak. All of the TOS movies weren't blockbusters but TNG was still made.
I'm not sure we're talking about the same thing. Those movies may have drawn inspiration from the earlier TV versions, but they weren't literally set back in the old timelines. Ed Norton wasn't playing "David Banner" and, of course, the character of Betty Ross was never part of the old HULK television series.
Similarly, BATMAN & ROBIN may have been trying to ape the style of the Adam West series, but it was still set squarely in the then-current movie timeline . . . as demonstrated by the fact that Batgirl was depicted as Alfred's niece, NOT Commissioner Gordon's daughter as in the 1960s TV series.
In the neither case, did the franchise restore the old continuity.
