2001 Space Odyssey: Please. Not unless you took a whole lot of acid and watched in the theaters in the 60s. Sure it captured the wonders of space travel and future potential of computers but the silly monolith creation story and the 15+ minute acid trip light show and floating baby makes watching the whole movie painful.
Apocalypse Now: More pretentious crap. Excluding the Napalm in the morning scene everything about this movie was beyond ridiculous. An Army Colonel that forms a cult that does nothing but dance around all day and kill people and then just gives up and lets himself be killed is just a beyond stupid premise. It is also the first movie to portray American soldiers as nothing but sexed crazed psychopathic killers.
With that said, Army of Darkness should be in the top ten
Apocalypse Now’s main problem began when some schmuck said, “ooh, Heart of Darkness” is such a good story! And, hey! Vietnam films are all the rage right now!”. Sometimes you put two things together and do NOT get a peanut butter cup.
