Four years after defeating the Dark Elves and two years after the fight in Sokovia, Thor now finds himself trapped on the other side of the universe on the wacky planet of Sakaar. Meanwhile, a new threat rises as the evil Hela, Goddess of Death takes over Asgard and plans to conquer the universe. In order to get home, Thor must compete in a gladiator match against the defending champion of the Grandmaster. Little does Thor know is that the champion is his old friend and fellow Avenger, the Incredible Hulk. Teaming with Hulk and his deceptive brother Loki, Thor must return home to Asgard in time to stop Hela and prevent the approaching Ragnarok, the apocalyptic destruction of Asgard.
Found this to be more enjoyable than the Dark World just a pity they killed off the Warriors Three so quickly.
