"The film was both a box office and critical failure on its release, but now it is considered to be both imaginative and influential. Variety claimed that "Despite a certain amount of production dash and polish and a few silly-funny lines of dialogue, Barbarella isn't very much of a film. /...production is flawed with a cast that is not particularly adept at comedy, a flat script, and direction which can't get this beached whale afloat." However, it has gained a cult following... /...and has had considerable influence on pop and film culture in the decades following its original release." - Wikipedia
