The thing about the 80s blockbusters is that they were great at delivering shameless and tasteless entertainment but without being distracted from the over-arching, big, profound, human themes that they tackled. I noticed this when I re-watched Uncle Buck, Planes, Trains and Automobiles and Cocoon on the TV over Christmas.
I mean, Cocoon, right, raises some really fascinating and fundamental questions about age, time, fate and the ethics of living a good life, but then it ruins all this by sending all the wrinklies up in a space ship where they can live forever. Planes, Trains and Automobiles basically fucks around for the whole film, dropping little clues to the ultimate emotional pay-off which comes like a kick in the face in the last five minutes.
The new movies are not, I don't think, as good at honoring thematic clarity, which means they do not really connect with the emotions at the same gut level.
