One From the Heart (1981)

 

The five-year romance of a window dresser and her boyfriend breaks up, as each of them finds a more interesting partner.

From memory: An expensive, audacious, but failed experiment by Francis Ford Coppola, it's visually stunning,  but narrative (and music) are simply not quite from the heart; it's all too obviously artificial.

Halliwell*: "Extraordinarily slim (for its cost) romantic fantasy which makes one wonder why, of all stories in the world, its creator chose this one. It does however boast attractive visuals."

Maltin**: "Lavishly produced but practically plotless romantic comedy...Dean Tavoularis' stylized Las Vegas set and the cinematography by Vittorio Storaro and Ronald V. Garcia are astonishing! Unfortunately, pretty images do not make a film...one of Coppola's most surreal entertainments. A must for the curious - others beware." 

Apocalypse Now (1979)

During the Vietnam War a captain is sent on a dangerous mission into Cambodia to assassinate a renegade colonel who has set himself up as a god among a local tribe.

I remember: Due to the advance hype for 'Francis Ford Coppola's Vietnam' movie the film did not fully live up to the expectations, but did provide unforgettable scenes and an feverish atmosphere of war madness.

Halliwell**: "Pretentious war movie, made even more hollow-sounding by the incomprehensible performance of Brando as the mad martinet. Some vivid scenes along the way, and some interesting parallels with Conrad's Heart of Darkness, but these hardly atone for the director's delusion that prodigal expenditure of time and money will result in great art. (The movie took so long to complete it was dubbed Apocalypse Later.)"

Maltin***1/2: "...a mesmerizing odyssey of turbulent, often surreal encounters. Unfortunately, film's conclusion - when he does find Brando - is cerebral and murky. Still, a great movie experience most of the way, with staggering, Oscar-winning photography by Vittorio Storaro."
