Agreed. It's interesting to me how some cultural products are completely dated and "of their time" when you experience them decades later, whereas others remain timeless. I'm reasonably sure that Casablanca will still be receiving praising like this in the 2210s. Part of what makes it so compelling for me is exactly what the author identifies toward the end -- a lot of the actors in this movie really are WW2 refugees, and you can see it in their performances. It's impossible for me not to cry when I watch the scene in question.
