In your opinion what factors contribute to a good movie?

There are several factors that contribute to a good movie. Firstly, I think the conveyance of the meaning is the most important factor. However the meaning is good, however the actors are popular, if the movie cannot convey the meaning properly, the movie becomes nothing. Furthermore, we all know that the movies that inspire us always inscribe their meanings on our hearts. Secondly, the OSTs also have a big role in making a good movie. Moreover, background music create atmospheres. It helps us predict what will come next. Lastly, actors' performance is also impotant. Some actors are so absorbed in the situation of the movie that when they cry, we cry, too. Good actors' performance makes us focused on the movie during the whole playing time, controlling our emotions, making the movie "a really good movie". For these reasons, I think the conveyance of the meaning, the background music, and the actors' performance are the most important factors of a good movie.
