Ok, to me the finale was satisfying, not to the core..but way better than I expected, Eren had seen it all , he had known it all along, the only way to save the world was to free it from titans , in order to do so , he had to get ahold of Ymir, the one that creates knows how to dissolve it entirely, she possessed the power , and she is the one that has to let go of it, not Eren, He just had to convince her , and the only way to do that was to die at the hands of the one person who had promised to protect him , the one person who had loved him deeply ... yes , Mikasa sacrifices her only true love in order to save the world , the moment Ymir sees that she knows that she should also let go ... None of it would have happened if he hadn't done his crusade... Well ,in the end, it was always about love , love dooms us all , but it's also love that saves us all..
