Thor: Ragnarok

Doomed Siblings will always be my favorite trope. "Do you truly think so little of me?" > "Loki, I thought the world of you." It's the way Thor has been fooled by Loki, for too many times—yet Thor still trusts him, again and again. Loki always wanted to be Odin's favorite, but he's always been Thor's favorite. I can't believe it took 12 movies since "Thor 1" for Thor to realize as to why he's called "God of Thunder".
