Intriguing as an artifact of the bygone hippie era. Barbarella's personality and the world she comes from give something of a sense of what the movement was gunning for (no army, no police, no military). But yeah; it's pretty terrible. Barbarella is nearly worthless as a protagonist, constantly in need of saving, killing without compunctions (in spite of her backstory), and having almost no part in the climax.
Overbearing 1960s sci-fi sexploitation film; I love everything about it. The story is so far out in left field, but doesn't ever seem to take itself too seriously, which reflected in my mood when I watched it for the first time. Barbarella's sexually-charged quest to find and rescue scientist Durand-Durand just escalates in ridiculousness with each passing minute in such a great way.
