However, in reality, that might not be the case at all. In an interview with The Associated Press (via ET Canada), JJ Abrams mentioned that The Last Jedi did not alter the direction of the story he initially had in mind while making Star Wars: The Force Awakens.

I think it’s fair to be disappointed that the legendary characters like Luke Skywalker and Han Solo didn’t receive grand heroic moments before their demises (I personally love how the OT characters are utilised in the new trilogy, but one man’s meat…). However, the whole notion that “Rian Johnson destroyed Star Wars” makes no sense, considering it was JJ Abrams who killed off Han Solo and used Luke Skywalker for a whopping 2.3 seconds in The Force Awakens. Based on what we see in The Force Awakens, as well as what Abrams has been saying in interviews, Rian Johnson did indeed continue Abrams’ story in a manner in which he’s satisfied with. It also makes the mystery of Rey’s parentage all the more interesting, since in The Last Jedi, Kylo Ren tells Rey that her parents are “nobodies who sold her off for drinking money.” Did JJ Abrams intend for that to be the plot right from the get-go or will we discover that there are aspects of Rey’s past that even Kylo Ren in unaware of? There’s also the unceremonious and shocking death of Supreme Leader Snoke at the ends of the rage-fuelled Kylo Ren. Abrams has mentioned in the past that it was always their plan to bring back Palpatine in the new trilogy. So perhaps Abrams had it in his mind to kill off Snoke as well?
