Every so often, one sees a movie and says "this is the best movie I've ever seen---I probably won't see anything as moving as this. And sure enough, something comes along that is as good and many times better. The human condition is so varied and multi-faceted that one may never exhaust all the permutations of artistic expression that can be shown. For example, when the TV science fiction hit "Star Trek" came out I thought it was so fantastic. But when "ST The Next Generation" came along, I had serious doubts that it could match the original. Then, as I marveled at the story lines and the extra dimension of character interactions, I felt that TNG is better and can't be topped. With each iteration something new was introduced that explored the vastness of human interaction and inter-species interactions. Etc., Etc.
