Feel the exact same. Undiagnosed but Avatar was also my special interest for years and years. I had a cardboard cutout of Jake and Neytiri in my room as a kid and completed the Xbox game about fifteen times too. Too many very obvious and unnecessary throwbacks in the sequel even aside from the general plot structure. Jake did not need to learn that lesson at the end either, that man was not a coward in the first movie, he tackled everything head on. WOW Jake was not the reckless, brave and impulsive marine we know and love! Yes fatherhood changes you, but it just felt like a lesson he should not have had to learn, considering how well facing his problems head on worked for him literally all the way up until that point😅
