Having been excited at the prospect of a gripping, historically accurate, realistic WWI film about the "Lafayette Escadrille," Flyboys is a big letdown. Devoid of historical substance, second-rate acting, predictable storyline - it shouldn't come as a big surprise that this movie was a flop at the theaters.Briefly, the CGI dogfights border on the ridiculous: aircraft in 1916 were hardly capable of the acrobatics and stunts shown throughout the film. More reminiscent of Star Wars than actual flying.Also: the portrayal of the Germans is laughable....all German pilots flying bright red, Red Baron-style, Fokker Dr.I triplanes, and led by the sinister "Black Falcon." (!) Come on!Recommended: "The Blue Max"
Output:
Negative
