An okay sequel to the first film which follows on from the events in 2012's Avengers Assemble.
It's important to watch the preceding movies, but not imperative (as it should be). Of course, it always helps to be familiar with the comic book character.
With Loki in the dungeons and Thor about to take his throne, the people of his kingdom face an invisible enemy who wish to destroy the universe as we know it.
In truth, the plot is a load of mumbo-jumbo, but it sees characters from the original film returning, including Natalie Portman as Thor's bit of fluff.
The action set pieces are what make the movie worth watching and it sets up the third movie nicely.

The third Thor movie and 17th of the Marvel Cinematic Universe is up amongst the better superhero movies and is certainly the best of Thor's individual adventures.
The action and adventure commences immediately, with Thor defeating a fire demon to prevent the fabled Ragnarok (a prophecy foretelling the end of Asgard, Thor's home planet).
On his return home, he discovers that his mischievous brother Loki has been impersonating their father, and has allowed their world to become vulnerable to attack.
They visit Earth to locate their father, and are met by their older sister, Hela, The Goddess of War, who takes over their home and leaves Thor stranded on a junkyard planet where he becomes involved in gladiatorial combat for a dictatorial leader's entertainment.
Thor: Ragnarok had plenty of action, adventure and comic relief to entertain throughout its duration, and sticks closely enough to the source material to keep fanboys happy.
Some of the visual effects aren't quite as polished as others (the giant dog looks rather poor), but the Incredible Hulk effects have never looked better.
As always, a post-credit sequence offers a teaser for the next in the series of films (2018's The Avengers: Infinity War). One minor gripe is that Natalie Portman's character is lazily written out, replaced by Tessa Thompson's Valkyrie, who many fans seemed to like, but I found her character irksome and the performance serviceable at best.
If anything, the film is too fun for its own good, but I don't really see anything wrong with that.
