Avatar 2
I did not watch the original Avatar in 3D. I watched it in 2D, thought it a good enough popcorn movie and since then haven't seen it in 10 to 13 years. It's not a movie that has had any meaningful impact in the film industry. It didn't launch any stars. It didn't spawn any knockoffs. The novelty of 3D fizzled out. In fact I don't believe it had any impact in pop culture in general, other than the running gag of the sequels taking forever to come out.
The other thing the movie's known for I guess is the not that original observation about the movie not being that original. Yes, it's every invader-turned-savior plot ever. It's Dances With Wolves, Pocahontas, Last Samurai. You don't say. Indiana Jones is superfluous in Raiders, the door in Titanic was big enough and nobody asks for the letters of transit in Casablanca.
Anyway, Avatar 2 is a bit like T2, in that it's about a "found family" on the run (unlikely allies et al) and the villain has been significantly upgraded. There's also a little bit of Titanic during the climax. In general I think I enjoyed it more than the original. It had sharper characterization, more interpersonal conflicts, and the benefit of a slightly more unpredictable plotline. There's a bit more suspense too since we keep cutting between the heroes and the villain, all of whom grow stronger or simply more prepared for a confrontation. And yes, the spectacle is top notch. Cameron is very deft at preparing action as much as he is at delivering it. He clearly has a fascination with learning and mastering and has a very specific, exciting way of showcasing it. Action is transformative too; a set piece can go back and forth between being airborne and underwater or cutting between different characters and the excitement never wavers.
I think the biggest weakness is the dialogue. Worthington narrates the whole thing in platitudes, droning on about family, happiness, light and darkness, whatever you want. Sometimes he explains what we just saw or what we're about to see, and the movie really doesn't need it. Some of the lines spoken are also really bad - like caption this scene bad. No spoilers but most involve a bad guy who keeps prattling about money.
Lastly... There's a dark as fuck moment towards the end that goes completely unacknowledged and unexamined by the characters. Even if they're going to address it in the sequels, I just don't believe that it would go unchecked like this. It's a complete moral aberration. How do the characters just walk away from it? Did I miss something?
