Other critics are more demanding. M. Keith Booker writes: For their part, the Coens deny any intention of presenting an allegorical message. They chose the detectives' names deliberately, but "we just wanted them to be representative of the Axis world powers at the time. It just seemed kind of amusing. It's a tease. All that stuff with Charlie – the "Heil Hitler!" business – sure, it's all there, but it's kind of a tease." In 2001, Joel responded to a question about critics who provide extended comprehensive analysis: "That's how they've been trained to watch movies. In "Barton Fink", we may have encouraged it – like teasing animals at the zoo. The movie is intentionally ambiguous in ways they may not be used to seeing".
