It's on the Internet though. It must be true! I read it on Wikipedia.
I saw it... on a YouTube fanmade conspiracy video... I think it was called Midnight's Edge.
ETA: Oh, FFS, I just actually watched the video. I can't even... I don't know
how anyone could take this seriously. This vlogger is a complete moron. He's comparing Luke Skywalker to an app on his smartphone? Come on! Then, he suggests that if we were okay with Luke dying that we should reconsider if we're actually Star Wars fans? Come. On! Not only that but 90% of the video, he calls the subject "Crazy Kathleen Kennedy?" Yeah, because that's a way to make your point. Not to mention that he's using MovieWeb as a source, which is almost as bad as Midnight's Edge.
It doesn't seem to even occur to people that Star Wars is a multigenerational story. The people who I assume most of who have posted on this thread have had their movies back from 1977-1983. The prequels were for the next generation and the sequels were for the generation after that. It frustrates the living crap out of me that people don't understand that and have such a level of overentitlement that if things don't go their way then its the end of the world. Its not. Sorry.
Maybe Trevorrow did want Luke to survive? So what? Decisions had been made. If you took that out, the structure changes. Luke's sacrifice makes him bigger than he could be alive. Having him survive, or even worse, actually show up on Crait for real and survive, would be fucking ridiculous. Luke becomes a legend in his death, far greater than he could handle in life. You take that away, I think it would cheapen his effort.
Its unfortunate that Carrie Fisher died before Episode IX could be made. I wanted very much to see her in whatever role was planned. But changing the dramatic structure of what happened before just doesn't make any sense to me. We have to deal with what happened. So does Lucasfilm.
I'm sorry people are so frustrated because they didn't get what they wanted. But at the end of the day, as much as I love Star Wars, it is just a movie. Getting this upset about it as this guy did? It ain't worth it.
