Avatar: The Way of Water was a great continuation of the 2009 Avatar, but it did manage to repeat James Cameron’s original movie in eight big ways. Due to Avatar: The Way of Water being a sequel to Avatar, it makes sense that both films share a lot of parallels. The Avatar franchise is linked together by a common story, characters, and themes, meaning that the DNA of each film will be essentially the same as the series continues on. However, it is hard not to notice some of these parallels in Avatar: The Way of Water, like these eight.
