Jesus, now I really do feel old since I lived through the 80s as a teenager. But I would put Empire Strikes Back, Aliens, Terminator and Full Metal Jacket near the top of the pile for greatest 80s movies.
As for Labyrinth, nothing beat seeing Jennifer Connelly in the ballroom scene for the ultimate "Girl Next Door" who was drop dead gorgeous, with the possible exception of Phoebe Cates in Fast Times At Ridgemont High (and only because she got nude).
