Extremely disappointed by the movie "John Carter" (but at the same time interested in the universe that is mentioned there), I wanted to read the novel that was originally. Although I took: the March cycle is what might be called the station of literature, no artistic pretensions. The book (or rather the books since this collection includes five novels) is very catchy, reads with a lot of fun, like a great cartoon without images ... The author does not lack imagination and follows with interest increasing the tribulations of a hero as one does not go, bellicose, charismatic and chivalrous. The universe is one of unbridled science fiction, precursor of heroic fantasy, where cotoie swords, telepathy, futuristic weapons and airplanes. Can be read from 7 to 77 years old, if one has kept a little dream in the back of his head ...
