Could remake it but less Avant Garde.
I rewatched this recently in honor of David Bowie's recent death. I think the film should be remade but make it more linear and less avant garde. One needs repeated views to catch all the subtext.
The main characters age (other than Bowie) to indicate time progress.
Nothing wrong with the gratuitous female nudity.:-)
OT: There's only one family on an entire planet?
That's just my two cents.
