These type of flicks can be entertaining, especially if you're already the choir being preached to, but doesn't this Michael Moore-type of style start to get repetitive where you interview the most stupid people possible so that your point comes across with the subtlety of a sledgehammer because you don't have to debate your equal, and edit the movie to make yourself look like a demigod?

You haven't read any religous books, have you? I haven't gotten the chance to see the film yet, but it is my understanding that, from the 400+ hours filmed, some VERY respectable people were interviewed. The entire movie is currently being pitched to HBO as a series. You can't claim stupidity on someone who represents your religion everytime the silliness of the belief is exposed.
As for the people complaining about this movie mocking religion, it is your own fault. Religion deserves to be mocked, just the same as the belief in a Flat Earth deserves. And, yes, there are actually people who believe the Earth is flat. It is standard fare that when someone makes claims, but doesn't provide proof that they are to be ridiculed. Otherwise, many sales of the Brooklyn Bridge would see the light of day.
Why is it okay to make "The Passion of the Christ," but not okay to make "Religulous"? You make "The Greatest Story Ever Told," but any opposite of that film is criticized.

You invite the mockery you so despise.
