Before watching the movie:
This is a movie about a very large family. There’s currently a franchise of movies with the title that stars Steve Martin, but this doesn’t appear to have much to do with it, aside from perhaps a “suggested by” remake. I have the distinct impression that the modern version (which I haven’t seen either) involves a blended family, while this doesn’t appear to.
It does appear to just be anecdotes from a real family’s life strung together into a feature film. Not quite as attractive as a slapstick comedy with Steve Martin, but it should be fun and interesting.
