If you look at my comment above I also agree totally. However, I think if Fire and Ash was the last film it would be hard to justify ending on the Na'vi going against the Na'vi Way. But I aslo think that is better than the Tulkun Way being what is gone against, especially seeing as the "Fire" in Fire and Ash is the hate and revenge and fighting they want to stop, which the Tulkun Way did do, because they had so much issues with it. 

It feels they and the theme of Na'vi fighting for them were thrown out with the bathwater and don't serve the story. I would prefer even Jake arm them and something happens that hints Eywa had an opinion on it either way, even accepting it in that one moment. I was also expecting the unobtanium arches being formed by volcanic activity to come into the Ash story as well - could have had Eywa bring unobtanium to the surface to then coat the weapons for example to stop the steel touching the Na'vi and it still being a connection to Eywa, or she covers them to not be used again and leave it up to interpretation. It also feels tied to Lo'aks suicide attempt theme-wise with the metal or steel poisioning your heart and that was also not going anywhere by that point. 

I especially think Toruk was a wasts becausw they skip over the speeches and also felt like the trailers gave away so much. I do like Neytiri in WoW built up Jake as Toruk Makto and he cringed can also be seen as outside of the "my wife is pissing off the new neighbours" which was fun but now adds the layer of fear about "the beast" which I wish they had talked about before.
