There are several non-pornographic movies that feature nudity and are considered to be well-made. One example is Blue is the Warmest Color, a French film that received critical acclaim for its emotional coming-of-age story and its graphic sex scenes. Another example is 9 Weeks, a mainstream movie that features extensive nudity and explicit sex scenes, but is not considered to be pornography. Body Double, 3D Sex and Zen, and Wild Bunch are other examples of non-pornographic movies that feature nudity and are considered to be well-made.
It's important to note that the inclusion of nudity in a movie does not necessarily make it pornography. Many non-pornographic movies use nudity to convey a specific message or to add authenticity to a particular scene, while pornography is primarily intended to sexually arouse the viewer. Additionally, the rating system used by film classification boards, such as the NC-17 rating, can be subjective and may not accurately reflect the content of a movie.
