Thor is on the other side of the universe and finds himself in a race against time to get back to Asgard to stop Ragnarok, the prophecy of destruction to his homeworld and the end of Asgardian civilization, at the hands of an all-powerful new threat, the ruthless Hela.
When watching Thor: Ragnarok, you could have easily titled it Guardians of Ragnarok. A lot of elements from the Guardians films are here. That doesn't mean the film is not good. It's quite the opposite. It's the best of the Thor films and you can tell that Taiki Waititi's imprint is on this. There were a couple of moments where it was a little silly, but it is a pretty damn good ride, nonetheless.
