Effects are impressive. Good if you're 16 or have the mentality of a 16 year old. If you've seen a movie or two in your life, you'll know how each science ends, who exactly is going to die, and how will the protagonists respond. Also, about half of the movie has no plot, just visual effects, so make sure to pack a lot of patience.

The fantasy is really lacking, especially compared to other universes such as Marvel, LOTR, star wars, or, you know what, Rick and Morty. There are like 7 species on this entire stupid planet. One type of bird. 3 and half type of fish. Nothing makes sense anymore.

In retrospective, I was sure I loved the first Avatar. This movie reminded me that I didn't, and was probably inception-ed to believe I did.
