I couldn't agree more with Jazzy11 Jazzy11's review is spot on. He said, very succinctly, many of the same things that had occurred to me as I watched.
One area that seems to need to be explored better, though, is Fassbinder's near Nostradamus like vision of the eventual hegemony of the western powers/NATO alliance. Naturally, this is quite evident in this particular version, but it's all there in the source material too. There is even a hint at the neo-conservative movement and preemptive war doctrine of that came to preeminence at the end of the 20th century and actually took root during the Bush administration. Both on a literal and symbolic level, the message is unmistakable.
Watching any version of "Berlin-Alexanderplatz" simply reinforces, to the acute viewer, that we are all part of a wondrous mystery filled with universal truths that were prescient then and prescient now.
