For someone who studied in europe, it's a fairly bland painting. I guess it embodies everything I find constrictive about american culture at the time in its subject matter? To me it isnt even interesting in a satirical way.. which the artist has denied in any case. It's become quite popular for clearly being a crappy work of art(yes, in my opinion), that happens to connect/did connect with a lot of people who were surrounded by conservative views and roots. It's popular because some people thought it was a funny depiction of how dull simple life is.
but again.. only my opinion.
