Just saw Avatar Way of Water on an IMAX screen and was blown away. I find sequels are rarely as good as the original but James Cameron knocked it out of the park with Way of Water. The story unfolds over 3 hours but it sure didn't feel like that long to me because this is a cinematic masterpiece. I've binged entire seasons of shows for more than 3 hours so the run time isn't an issue.
The movie had themes of family, sibling rivalries, and the love a parent has for a child. Go see it!
