Well the other guy is right, in a way. The concept was that 4 movies would run LIVE at the same time on different channels, and you would edit the movie yourself by changing between the channels. You could end up watching a very confusing movie if you changed the channels on the wrong times. But if you changed at the right times it was not as confusing. The cool thing was that everybody saw the same plot and the same people, but everybody saw a different movie.
BUT later the 4 directors would edit the movies down to one movie that was on t.v. the next year, and I THINK that was a very good movie.
But everybody likes different stuff
