To be honest, the season started a little weakly and I initially suspected that the writers would lose the thread and get lost in countless confusions. But with the last 3 episodes and a finale in which all the threads (including a small detour into the first season) come together, they have achieved a masterpiece. The motivation of the One and Loki's decisions, which go against his original intention but ultimately lead him to his desired fate, build a formula that goes beyond Spock's sacrifice in Star Trek II: "The needs of the many outweigh the needs of the few - or the one". While Spock (from his point of view) basically didn't change his own fate (he acted completely logically), we observe something completely different with Loki: We witness a comprehensible, heartbreaking character development of a misunderstood, even pitiable would-be villain whose own mirror image leads him to the ultimate self-sacrifice.
What a ride!
