The Last Jedi
This title is memorable, but like ROTJ I don’t think it represents the film. Luke is only one part, not the driving focus (if say the Resistance were praying for Luke’s help, it might have worked).
They weren’t? News to me.
But at the very end, Luke says he will not be the Last Jedi. This is really annoying to me. And I get it. Subversion of expectations! But a title is more or less a promise that something will happen.
That’s an oddly stringent way of looking at it. The title is about the idea of Luke being the last Jedi, and whether he will fulfill that title or not. Not to mention, he’s referred to by that title twice in TFA, and it’s not an inaccurate descriptor of him in TLJ itself - looking at it another way, he’s “the last Jedi” left, or worded differently “the last” of the “Jedi.” So really the title is a question (not a promise), saying “he’s the last Jedi now, will he be the last Jedi forever?”
Otherwise I agree with your rundown (except for maybe TPM).
