There were so many plot holes that it just felt like you were watching a knockoff/fan written version of the first. Even the animation was spotty at times, low quality when groups of people were present. No main character, no character growth for majority of the characters. Many additional characters that were unnecessary, changes in human technology seem to be downgrades. What happened to unobtanium? And what happened to Jake's ikran, he just abandon it all together? Goes from being ignorant Jarhead to a scared military father??? Genuinely felt like every scene was an opening scene and not a single character had any growth or spiritual connection to the new reef none of them.
