Hasn't it been pointed out numerous times that Michael Moore flat out lies?
Not only does he chop out speeches, and reassemble them to say something completely different, but he has flat out lied in many of his statements.
He uses facts and numbers made up, claims documents say things that they don't, etc.
If you define educational as something that adheres to your particular flavor of political views, then I'm sure the film is quite educational.
And for the record, there is nothing wrong with going to see Spiderman, or some action flick for the purpose of enjoying an action flick. They are movies after-all. If I want to be educated, I'll look online, pick up a book, or attend a class.
