The use of the long camera shots is very impressive and I have never seen it before in a movie. The long camera shots shows the viewer the skill of the actors and actresses. It shows their ability to stay in character for long periods of time and the extensive training they would have had to go through in order to have memorized the entire scene. It is a very unique style that you do not see very often in movies nowadays. It brings a different feel to the movie that movies with many cuts and short takes don’t. It gives a sense of fluidity and ease to the story, connecting everything together very smoothly.
I agree that the long shot adds a sense of fluidity to a movie that excessive short scenes and cuts don’t allow. However the thing I find most interesting about long takes is, as you mentioned in your post, the fact that the actors have to take a long time and a lot of effort to memorize and practice their lines. I imagine that it would be an immense amount of pressure put on them due to the fact that many of these long scenes are one take shots.
