I really enjoyed the first Avatar. I saw it in IMAX 3D and found it visually stunning. I was excited to see this one, even with the daunting duration of over 3 hours. Within the first 30 minutes, I would have walked out if there hadn't been so many people sitting in my row. The story was blah, the visuals were not as stunning as the first one, and the acting was weak. There were people who just disappeared from the story and plot lines that didn't add anything but were fillers. No need for big name actors, you can't recognize anyone (plus everyone looks very similar). Scenes stolen from Jurassic Park, Jaws, and many other similar movies. The whole thing could have been wrapped up in 45 minutes to an hour..
