Huh, well, asking someone who grew up in that era what the best movies of the 80's are, may not match the list 20 somethings come up with who didn't experience the movies first hand. 
That's all I got on the RS list. 
And a lot of those movies were good, but great? Some of those in the list are fluff type films I consider date type movies, like Pretty In Pink, Sixteen Candles, and St.Elmo's Fire. While they might have good stars in them, one watch is more than enough for one lifetime, thanks. And it's hard for me to consider any comedy movie really great, because since it's a comedy, it's obviously not taking itself seriously in the first place, like Ferris Bueller's Day Off, Weird Science and Fast Times At Ridgemont High. Those films just don't measure up at all when compared next to Blade Runner, The Shinning or Full Metal Jacket. 
And some movies I consider great like the Godfather part 3, were actually filmed in 1989. But it wasn't released until December 1990.
