There are a lot of laughable things about the movie, mostly what a dork the main protagonist is, but having lived through that era, he’s actually not all that far off from the way a young man from his culture would have acted in real life. He really looks up to the woman who, to him, has made a big change in her life by doing something different even though the “something different” is that she moved across the bridge to Manhattan and took a couple of college classes. I have actually read about people who lived back then in places like Brooklyn and Long Island and yet never went to Manhattan - it was like another country to them.
The subplot with the brother who is a priest and wants to quit the priesthood is also unfortunately true to what was going on in the US church at the time.
