I think I've only seen "It's a Wonderful Life" once in its entirety. I like the story, and it shows us how things intertwine to form what they are. Another one for that that I like is "The Butterfly Effect". Great story. I often find myself thinking about the butterfly effect itself in most instances in life especially when things get rough. Everything happens for a reason and has its purpose.
I like "The Breakfast Club" because it shows in a wonderful light that no matter how different we think each other is, we are all really the same and it is merely our perception of things that is different. I LOVE that movie.
But really, that's how I look at every movie, and the meaningless ones I don't even bother with. I realize that some people need them for entertainment, but if I can't get anything meaningful from them, I don't bother. There's lots of movies that I used to like but don't anymore. I guess I have grown beyond them. But, there are those few that hang on through the years that still have some meaning for me.
I don't know, maybe it IS a generational thing with Breakfast Club, but I've loved it since I was a kid and I still love it today.
