Sounds like you've missed the point of every piece of art ever created then, given it all is trying to tell a story or send a message from the artist's perspective. I watched that movie and didn't pick up on it as being preachy or educational about a particular ideology, at least not in a heavy handed way. Maybe you brought some of your own baggage to the viewing.
There is a difference between 'education' and storytelling though. Even you allude to that by classifying movies as "tell a story or send a message". Sometimes people don't want a message.
Most people don't know what they want.
It's the books/songs/films/paintings that are clever enough to both entertain and contain a message that resonate with viewers. These then go on to be dear to our hearts and lauded as good art, as classics. As a quick example, look at the difference between Terminator (one) and Terminator Two.
They both have robots and car crashes and gun fights and all that good stuff that makes it exciting and entertaining but its the second one that takes time to reflect on what it is to be human and how human nature is not always a good thing.
It's one thing to contain a message, it's another thing to be subtle or preachy about it. Being subtle about it allows viewers to go , oh cool, there's robots!, or damn, the human race is already fricked, let alone if we invent AI. If there is some debate about the subtlety with this one, carry on, let's hear it.
