The first one was definitely a massive cinematic event because of its visuals and the second one was also an event in itself because it was the sequel to the first film. If the third is released any time soon then I might reconsider going to see it. The gap between the first two was sort of what interested me but the second wasn’t as visually impressive for its time as the first. I would be surprised if there were many Avatar “fans”, though. It just doesn’t have anywhere near enough depth to its characters or their world and a lot of its themes about spirituality and indigeneity feel like some borderline cultural appropriation white guilt stuff. The people who are really into that aspect of the films are revealing quite a lot about themselves and their own insecurities, I think.
