The whole article is a spoiler.
BTW, as a Christian I see the movie as exposing the meaning of life without God.
meaning = meaninglessness
From the article:
"..... The Last Jedi spends an entire film demolishing organized religion"
That was the intent of the nihilistic atheists who wrote it.
That was "the message."
And then the article's author says this:
"It didn’t have to be this way. Hopelessness isn’t inevitable in a story about failure. Take the other major modern myth, The Lord of the Rings. Failure is central to its plot, yet it is never hopeless. Tolkien wrote, "I am a Christian and indeed a Roman Catholic, so that I do not expect 'history' to be anything but a 'long defeat'—though it contains (and in a legend may contain more clearly and movingly) some samples or glimpses of final victory." In this vein, Tolkien's characters all see their quest—to take a magic ring into the very heart of enemy territory in order to destroy it—as a desperate venture, nothing more than "a fool's hope." Yet they fight on, nonetheless, because of faith in an ultimate victory and inspiration from an ultimate beauty."
