Odin (Anthony Hopkins) recalls when his father Bor and the warriors from Asgard vanquished the evil Dark Elves and their leader Malekith (Christopher Eccleston) that wanted to send the universe into the darkness during the convergence of nine realms unleashing the powerful weapon Aether. Mallekith escapes and Bor hides the Aether in-between two stone columns.

In the present days, on Earth, the scientist Jane Foster (Natalie Portman) that is waiting for the return of Thor, investigates a gravity phenomenon in an abandoned factory with her assistant and her intern. She finds the column where the Aether is hidden and the substance possesses her. In Asgard, Heimdall (Idris Elba) reports to Thor (Chris Hemsworth) that Jane has disappeared. Thor returns to Earth and finds Jane; but when he sees that he has a strange energy protecting her, he brings Jane to Asgard to be healed.

However, Malekith also awakes and goes to Asgard to retrieve the Aether. After a bloody battle, Frigga (Rene Russo) is murdered by Malekith and Thor proposes treason to his warriors friends of Asgard and teams up with Loki (Tom Hiddleston) to seek revenge for the murder of their mother and to vanquish Malekith before he destroys Asgard with his Dark Elves.

"Thor: The Dark World" is another great adventure of Thor. In this movie, Thor makes the most unlike association with Loki and the result is a wonderful movie. The scene of Loki fighting with Thor is the best moment of "Thor: The Dark World". Chris Hemsworth perfectly impersonates Thor and the conclusion surprises. Last but not the least, the movie is to be watched until the very end of the credits because there are two additional scenes in the credits. My vote is eight.

Title (Brazil): "Thor: O Mundo Sombrio" ("Thor: The Dark World")

The film overall has it's fair share of holy s**t moments that defy all levels of credibility, even for a comic book/sci-fi/fantasy movie. That whole business about the Aether winding up in Natalie Portman's body was just a little too much to wrap my head around, especially after it was assured that the heroes of Asgard buried it so deeply to avoid detection by the Dark Elves.

Probably the best way to approach this film is to just sit back and get transported between the realms of Earth and Asgard without thinking too much about it. As an actioner there's plenty of it. As a story, there's just too much going on with events seemingly occurring because they were written that way instead of there being a rationale for them. I mean, one minute Thor's hand is cut off and then it's back again - wait a minute, what!? And with the emphasis on the Dark Elves I found a lot of Asgard suspiciously resembling places seen before in Rivendell. If there's going to be a Thor III, maybe a little more thought needs to go into it.

Following on from the events of the Avengers movie, Thor is back in Asgard, delivering Loki, who is damned to spend an eternity in the Asgardian dungeons.

Jane is in London, still pining for the titular character, as she hasn't seen him for two years, but still holding out for him.

But there is a new threat from the dark elves. They seek an elixir type essence that will cause darkness amongst the nine realms.

Jane however has found a portal into one of the realms, and gets infected by the essence. Because the dark elves can trace this source, Thor rescues her and takes her back to Asgard, much to Odins dismay.

But the elves plan an attack on Asgard, and after many lives are lost, Thor realises that only one person can help him, and he's damned for the rest of his life....

The first movie was wonderful. Not only was it exciting and refreshing, but it was one of the funniest Marvel movies released yet. This however takes a huge step back, and really taints phase two of the Marvel releases.

Hemsworth is as good as ever, as is Hiddleston, but apart from Portman, it appears that the rest of the cast have been sidelined, so Thor and Loki can carry on their war of nerves.

It's also very convoluted, narrative is lost as there is so much going on, and by the end of it all, you wondered what on earth went on, an also what happened to a few of the characters, there are plot holes aplenty.

The humour what was wonderful in the first movie, feels really forced in this, and instead of causing unexpected laughter, had me rolling my eyes as to how silly it felt. Dennings is a thorn in the movies side, she is a parody of her character from the first, and ruins every scene she is in.

The best joke in the film, which was in the trailer, steals from Raiders of the Lost Ark anyway.

Visuals are bland and boring, and Asgard feels like something from The Phantom Menace, combined with Flash Gordon, and the rest of the realms could have come from any Lord Of The Rings movie.

Its a shame, because Marvel know they have a winning formula, but here it feels like they are just in it for the money, and all the cool references and a brilliant cameo, cannot save such a disappointment.

Many will call it Thor-some and other play on word praises.

But for me, and I really hate saying this because Hemsworth is really good, it's pretty Thor-ful.
