In the unfortunately limited space of the Francophone SF was fortunate to have a few stars of the first magnitude, including Pierre Pairault, which (just for fun) launched into the genre known as Stefan Wul. He was twice adapted for the big screen by René Laloux, the first time for "Oms en série" ("Fantastic Planet"), the second ("Time Masters") for the main news of this code. Brought to the author by this last film, I had the pleasure of discovering a goldsmith in the original universe, fascinating and credible both. A light writing, captivating, a style that no longer exists today, but can you really say 'this date'? It probably dates when you consider that many current authors seem obsessed with the present, and try all kinds of extrapolations into the future - to be recognized by generations of the same future as "anticipatory masters"? Wul would just tell great stories in distant worlds, and it injected a massive dose of imagination - with what to science and complement poetry. The escape is immediate, as the emotion that I again hugged by reading the conclusion of the new (besides, what may have been thinking in the late René Laloux, the end of "The Orphan" is otherwise better constructed than its variant of the "Masters of Time", even though I really like the film). Each course has its preferences for science fiction; mine found satisfaction in the subtle balance distilled by the author. In conclusion, saying that otherwise invite you to read and reread Stefan Wul? I confirm, that book it is a very good introduction.
