To like what one likes is a valid way of assessing a movie’s worth, however, often this judgment is made uncritically, passively, and without solid reasons. In contrast, to know why one finds a film to be flawed or fantastic and to be able to see and communicate how it is skillfully or poorly constructed is to experience a broader and deeper sense of appreciation.
