Damn, we have to prepare a slingshot. Newman would have been so great in Star Trek!
I'm from a generation born after TMP. Many of us don't really appreciate this looooooong and ugly movie and find TWOK well better.
For me, TWOK is the real start. TMP is more a kind of cute reunion. Hey look, I'm now admiral and I don't really like it, so I decided to kick the kid from my old chair and to interrupt Bones's disco solo career.
It's really TWOK that established the universe of TOS movies where the Enterprise and her crew are both aging.
