Agreed. The surprise factor was right up there with The Matrix for me. (Don't read that wrong please- this movie is not on par with The Matrix in my opinion, they just both supremely surprised me.)
I went with a work group for free, which was the only reason I attended. It was late after a long day, and I didn't really enjoy the first hour and even started to fall asleep. But after it turned into Water Mode, I was hooked. Very well executed. I liked it far better than the first Avatar.
Same. I don't think it's a great film or anything, but it's spectacle and visual style is wondrous to behold, especially in 3D. I don't think it reaches the heights of other blockbusters from this year like Top Gun: Maverick and The Batman in terms of storytelling but it's miles better than crap like Jurassic World: Dominion which has the worst screenplay for a big budget film I've seen all year.
I was actually surprised at how invested I was in what was going off in Avatar 2 by the time the thrilling third act was unfolding.
