My favorite movie is "Gone with the Wind."
It is a very old American spectacular drama. As I saw it some decades ago, when I was a high school student, I forgot the details of the movie. But , the famous last word said by the heroine, Scarlet Ohara putting up her right hand in the sky with a fist was really impressed to a 18-year-old girl.
"Tomorrow is another day."
It became my most favorite word as well as my motto in my life.
My worst movie is "Star Wars."
It is a SF directed by George Lucas in 1977. Although many people like this movie, I don't understand why it is so good, because I fell asleep during the movie. However, as this movie was very much influenced by a Japanese movie,"Seven Samurai" directed by Akira Kurosawa in 1954, it might be interesting if you compare these two movies. I would be glad if you do that and let me know your impression.
