Query: What's this movie about?

Having heard a lot about this movie, after seeing it, I utterly fail to understand what people like about it. The story: guy has a hell of a row with his wife, leaves her and his nice kids, travels the country with another wife, and finally leaves the mess around him in a spaceship. If this is what happens when aliens come down, well, let them please stay where they belong.
