Yes, all of the points you make are valid. Just about every movie from that era (and actually, from every era) has something about it that's not quite right. Another example is the film, 'The Miracle of Our Lady of Fatima'. In it, the Blessed Virgin tells the seers, 'In the end, God will triumph'. Of course, as we know, she actually said, 'my Immaculate Heart will triumph'. It's hard to know if this was an attempt to appeal to a wider audience of so-called 'Christians' who would be put off by such a clear display of Catholic theology, or if it was a deliberate attempt by Jєωιѕн Hollywood to undermine the message of Fatima (who knows, perhaps it was both).
Still, if you're going to watch a movie, you can certainly do a lot worse than these four movies. If you're watching them with your kids, though, you can point out the obvious errors/biases in them, i.e. provide your own commentary track, lol.
