I think that Wikipedia sums it up nicely:

Cashiers du Cinemart is a magazine and a webzine about independent film,published and edited by Mike White. The print version began in 1994 as a zine and evolved over the late 1990s into a more typical magazine format. The title is a reference to the French film magazine, Cahiers du cinéma. It ceased print publication temporarily in 2008, but continues on the Internet and via print-on-demand issues.

Cashiers du Cinemart openly mocks the basic tenets of film criticism and theory while championing underground and independent film. The magazine became known for its edgy writing and incendiary opinions, as well as its obsessive love for offbeat films.

In 2010, BearManor Media published a collection of articles from Cashiers du Cinemart titled Impossibly Funky: A Cashiers du Cinemart Collection.
