The MCU's worst-received Chris Hemsworth movies, Thor: The Dark World and Thor: Love and Thunder, could have made a bigger impact had they swapped their main villains. Kenneth Branagh's Thor established Thor, Loki, Jane Foster, and all the Asgardian mythology that continues to shape the MCU to this day. Years later, Taika Waititi's Thor: Ragnarok gave Chris Hemsworth's God of Thunder a breath of fresh air with a comedic take on the character. Their direct sequels, however, couldn't replicate their predecessors' magic.
