Should be considered as a play, not a movie. SPOLIERS
Considering this as a TV play, which is a much more accurate description than 'movie', it was OK, but nothing better or more original than many short stories and sci-fi shorts already existing.
I managed to get to the end, but the old guy dying idea was a bit trite and overly dramatic. Could someone really suffer a heart attack from getting shocking news which isn't even bad news? I don't think so, even if they were already suffering from a recent loss like he was.
