To enjoy Lawrence, you need to watch it on a large high definition television on blu-ray so you can appreciate the stunning beauty of the photography and immerse yourself in the film. You also need to pay close attention because missing one line of dialogue may result in not understanding a character's motivation. It's a movie that cannot be watched casually.
Frankly, I think that Lawrence of Arabia
, like many other great classic films made during that period, cry to be seen on a great big, wide screen, in a real movie theatre, with the lights down low, while sharing the experience with a whole bunch of other people, whether one knows them or not. The beautiful photography, the battle scenes, etc., the overall photography, scenery, characters, etc., are taken to the next level when viewed on a great big, wide movie theatre screen.
actually, I'm of the opinion that if you can watch a film on the small screen with no fancy tech and bluray etc, and it STILL has power, then seeing it on a bigger screen will simply be a more beautiful experience of something grand. but a good movie is always a good movie, even on a small screen. if it doesn't effect you on the small screen, very doubtful it will be any different on a giant clear one.
Seeing any famous film on a great big, wide movie theatre screen, with the lights down low provides an already powerful and famous movie not only with more beauty and a grander experience, but even more power, as well.
