Read the book of Joel again. (It’s pretty short.) What was Joel predicting? A chastisement of the Jews for their unfaithfulness, and afterward God’s salvation of and blessings upon the faithful remnant, with destruction upon those who persecuted them.
Then look again at Acts 2 where Peter says, in essence, “this prophecy IS being fulfilled.”
You did not answer my question. Regardless, we look forward to seeing the movie. It should be pretty good, and it is an example of those living in the last days seeing visions and dreaming dreams, much like St. Paul.
