Yeah i think we are just arguing semantics, forgotten or overlooked might be a better word than underrated. because objectively, you cannot even argue the fact that it is one of the most highly accoladed films that has ever been made since the invention of a camera lens.
AFI has it at number 30 on the list of top 100 movies of the last 100 years, Roger Ebert considered it to be the best film on the Vietnam War...and it goes on, heres the wiki:
Apocalypse Now was released to universal acclaim. It was honored with the Palme d'Or at Cannes, nominated for the Academy Award for Best Picture, and the Golden Globe Award for Best Motion Picture – Drama. It is considered to be one of the greatest films ever made. The film was also ranked No. 14 in the British Film Institute's Sight and Sound greatest films poll in 2012. The film ranks #7 on Empire magazine's 2008 list of the 500 greatest movies of all time. In 2000, the film was selected for preservation in the National Film Registry by the Library of Congress as being "culturally, historically or aesthetically significant".
Today, the movie is regarded by many as a masterpiece of the New Hollywood era. Roger Ebert considered it to be the finest film on the Vietnam war and included it on his list for the 2002 Sight and Sound poll for the greatest movie of all time. It is on the American Film Institute's 100 Years...100 Movies list at number 28, but it dropped two spots to number 30 on their 10th anniversary list. Kilgore's quote, "I love the smell of napalm in the morning," written by Milius, was number 12 on the AFI's 100 Years...100 Movie Quotes list and was also voted the greatest movie speech of all time in a 2004 poll. It is listed at number 7 on Empire's 2008 list of the 500 greatest movies of all time. Entertainment Weekly ranked Apocalypse Now as having one of the "10 Best Surfing Scenes" in cinema.
In 2002, Sight and Sound magazine polled several critics to name the best film of the last 25 years and Apocalypse Now was named number one. It was also listed as the second best war film by viewers on Channel 4's 100 Greatest War Films and was the second rated war movie of all time based on the Movifone list (after Schindler's List) and the IMDb War movie list (after The Longest Day). It is ranked number 1 on Channel 4's 50 Films to See Before You Die. In a 2004 poll of UK film fans, Blockbuster listed Kilgore's eulogy to napalm as the best movie speech. The helicopter attack scene with the Ride of the Valkyries soundtrack was chosen as the most memorable film scene ever by Empire magazine (although the same track was used earlier in 1915 to similar effect in the score written to accompany the silent film The Birth of a Nation). This scene is recalled in one of the last acts of the 2012 video game Far Cry 3 as the song is played while the character shoots from a helicopter.
In 2009, the London Film Critics' Circle voted Apocalypse Now the best movie of the last 30 years.
In August 2009, the head of the German Financial Regulator told the Bundestag Finance Committee that the failure of the "terrible" Depfa Bank, which was completely supervised by its Irish equivalent, led to the collapse of its German parent which forced Berlin to bail it out at a cost of €102 billion. The committee was told that the alternative was a run on German banks and the eventual collapse of the European finance system and "You would have woken up on Monday morning in the film Apocalypse Now"
I just have a different interpretation of underrated was my only point, wasnt a personal attack.
