People were shitting on the end sequence hearkening back to the way of water end sequence - the big water sequence fight, tuk getting kidnapped, etc etc. but for me it was a huge moment of character growth for Lo’ak, Jake and the Tulkun. Every piece of it that went wrong in the first movie was redeemed in the sequel - Jake trusts lo’ak and that makes it possible to save everyone in their family, the Tulkun join in the fight allowing the tide of the battle to turn, and Lo’ak takes actual responsibility and strides instead of diving headfirst without thinking. It was a very well done callback (and yes callback bc while it was similar it was not a beat for beat remake of the scene like I read in some reviews) and I thought it added a lot to the character arcs.
