Needs to be seen on the big screen
I saw this very recently at the Schauburg theatre in Germany, in its original format and on a curved screen. Although this was a German version the so-called 'dream-sequences' in 70 mm just knocked me off my socks ! The screen switches regurarly from 35mm to 70 and back again.
The story was intriguing and the use of some kind of pre-internet technology in the movie was pretty advanced for 1983 ! And I loved the last scenes with those construction robots going mad. A pity that everyone was speaking German !
