I love the old ones, my favorite is the original “Miracle on 34th Street”, I like the 1994 remake, but the original holds my heart. It’s heartwarming, and yet it reminds you of the reality of a nation not long out of the depression and WW2 (at least that’s how I see it). I also like “Holiday Affair” from 1949, which has a similar under current, but IMO is much more of a romance movie and less a statement on our society.
“It’s a Wonderful Life” is a favorite but I kind of OD on it, so it’s been a few years since I’ve seen it.
