Is the Elephant Man to David Lynch what Ed Wood is to Tim Burton? They are their most direct films.
It`s the one where he uses the least amount of abstractions and symbolic visual language for sure."facts are stupid things" - Ronald Reagan
This and The Straight Story.
The Elephant Man and The Straight Story are also Lynch's least pretentious films, and therefore his best. The only time The Elephant Man sinks into typical Lynchian pretense is the "nothing ever dies" star scene at the end.
Actually, believe it or not, Blue Velvet is the most straightforward David Lynch film.
