Movies are purely visual wrote Larry

But I thought they had introduced some radical innovation of having sound a few years back.

Aside from the possubility of having a greatly extended time span, allowing for a more complicated narrative, and much greater depth of character - but of course "allowed for" doesn't mean it gets done too often - the big difference between the two media is the degree of involvement.

With a film you're in the dark with the screen, and pulled ino it for however long it takes. With TV you are still in your ordinary environment, with all kinds of other things going on reminding you of that.   Seing the same movie on TV or on the big screen is a radically different experience. You find that out when you have occasion to watch a film in the cinema that you've seen many times on TV, and you realise you are seeing it for the first time.
