Taika Waititi made an outstanding job in bringing so much freshness and quirkiness to this movie. He has poured so much of his own imagination and attention to detail into building the characters looks, the visuals, Sakaar... and it really shows. All of this while pulling as much from the comics as possible. Add to this his biggest strengths which are humor, the balance of humor and drama and creating compelling characters that shine bright in his movies.
And from what i saw and the character interactions you could already see that he delivered again. Those Thor/Hulk/Banner interactions... Then that comic-con footage really showed how much Taika can extract out of small scenes, with his humor, dialog and style of directing. His characters shine bright like Thor, Hela, The Grandmaster, even Topaz with just a few lines, Korg...
I really believe this movie is going to have a massive impact in the MCU and most likely become one of it's better movies. In Taika we trust.
