The big underlying issue beneath the "KJV cult," I guess, is the NT Greek text it is based on, i.e. the Textus Receptus. Even though we have no early Protestant French version which can compare with the KJV in terms of literary quality and popularity, we have a few TR sectarians who promote very poor French versions (such as David Martin's) for the same reason. They actually advocate a global rejection of the later field of textual criticism, which really developed when older Greek manuscripts (such as the uncial codices of the 4th and 5th century and even older fragmentary papyrii) became available, and of all subsequent critical editions (such as Tischendorf's, Westcott & Hort's or Nestle & Aland's). Although the kind of textual criticism which led to the current critical editions is not above criticism (for a long time the search of an elusive "original" led to underestimate the inherent value of alternate editions, such as the Western text), the exclusive worship of the TR is true obscurantism, very alien to the humanist spirit of the Protestant Reformers and their principle of free inquiry vs. Roman magisterium. The TR adepts have, in effect, switched the infallibility they deny the Pope to the early Protestant translations: if the Reformers were right, the text they worked on has to be right (another good example of circular reasoning).
