You can scratch the "Maybe", because you're spot on! Lars is highly intelligent, likely a psychopath and is evidently mentally challenged. As a movie director he explores (and crosses) grey zone-boundaries and limitations of both actors, the scripts and in the end the moviegoers.. He's without question a legend among filmdirectors, for the concept of "dogma", his intellectual-eccentric antics in public (duh!) and also his "innovative approaches" to making movies. Personally i find him and his work only marginally interresting and would be hard pressed to recommend one (any) of his movies.
