Picked up Thor: Ragnarok on Blu-ray at the used place. (Gotta love someone who watches it once and gets rid of it.) I am really looking forward to Taika Waititi's director's commentary.
As far as the film itself, I love it. After watching the Team Thor: While You Were Fighting and Team Thor: Part 2 shorts, which were also directed by Waititi, I knew Hemsworth could do far more comedy than he was given, and this played that out in spades. Also as long time comics reader, seeing Jack Kirby's art style and color palate in action was a joy, Kirby Krackles and all. And in all that they managed to move a character arc on two of the characters who most resisted that in the MCU in Thor and Loki. Oh, and "Immigrant Song."
