AOT started out as a really great anime with amazing climaxes, plot twists, and surprises.
Everything was going well until the start of Season 4. Things after a time skip are always confusing, but changing the personality of the main character made everything really confusing. The plot became very complicated and mixed up with no respite for the viewers. The pacing was very fast with a lot of things happening at once that didn't even slow down to wrap my head around it.
I still continued hoping that things would make sense in the end. Unfortunately, quite the opposite happened and the ending was trash with none of the problems the characters were facing, getting solved... In fact, the anime portrayed the idea that the cycle of violence and hatred continued which made all the tragic deaths up to that point, meaningless.
Utterly disappointed and a complete waste of my time and anticipation
P.S.: The 2 stars are for Levi, the only character that had a proper ending.
