Watching these all, and then reading up on the movies afterwards (don't want to spoil my viewings or taint my own interpretation), it's shockingly obvious that almsot none of his movies were very well received upon release, except for Full Metal Jacket and the pre-2001 stuff, and even that wasn't ranking things as classic. Full Metal Jacket is, of course, viewed as a mixed bag today, but everything before is seen as a total, round the boards classic. For this reason, I am very very excited for my second viewing of Eyes Wide Shut, though I am keeping my expectations as low as humanly possible.
But 2001, A Clockwork Orange, Barry Lyndon, the Shining. . .all were critical mixed bags on release.
