As with much of film making, Dogme defined a set of rules which were a departure point, and film makers went about finding ways to break them. Some of Harmony Korine’s most important films like Gummo were influenced by Dogme but are not pure Dogme 95 films. Films that do abide by most of the rules, like Von Trier’s The Idiots are almost unwatchable - and that film in particular would be considered porn in the US. Those films are like a reference implementation in the software world.
