Like a play with Act 3 replaced by a ballet

Rating: 3/10 (10 February 2001)

It seems as though someone accidentally taped over the ending with some psychedelic animation (impressive for 1968 but otherwise pointless) and random clips from some other film... as far as I could tell, there's no conclusion to the story or explanation of the thing on the moon. The only message I can get out of it is to not trust computers. Perhaps I'm missing something... but if there was a conclusion/explanation in there somewhere, which cryptic crossword compiler wrote it?
