Another entry: Billy Bathgate. An already epically tedious period gangster movie was made even more tedious when I went to see it because someone thought it would be a good idea to cut out Nicole Kidman's nude scenes.
Obviously this is not a list of the truly most boring movies out there ( many favorites of mine are listed) but a list of mostly famous, popular or critically acclaimed films that evoked no interest in the viewer and seems mainly out here to provoke a reaction. That established now I can play the game. I can get snarky too! CLOSE ENCOUNTERS OF THE THIRD KIND. I spent an hour trying to figure out these aliens. I thought they must be very small because one of their ships that followed the others was the size of a basketball. But I eventually surmised in this, the only screenplay Spielberg ever wrote, nothing would be explained or need make sense. Everything was for effect. So the chandelier spaceship is just that, a chandelier spaceship. Aliens who could cross the universe would go down the chimney or through the vents of a house to fetch a little boy. Our protagonist throws things through the closed kitchen windows while his wife is on the other side of them for "comic effect". Indeed at the end we know no more about these aliens than when we started. Actually that's wrong. Thank goodness the wonderful Francois Truffaut was there to find out they know sign language. Hopefully he instructed them to land in some other country next time.
