Just a counter point I saw in analogue 70mm IMAX and found the frame rate caused flicker on my peripheral on some of the very white black and white scenes. So in some places the screen is bright white right to the edges and you catch a flicker. I wonder if digital would be the same or not.
That said both some of the effects and seeing the faces in larger than life close up.made it an amazing experiences. Also.the sound is as important as visual and the theatre I went to had amazing sound from shake your heart base to surround to great central speaker for dialog.
