What do you do when your most critically paned films need a sequel? Well, you combine them of course. While the individual Thor and Hulk movies were never the most popular of the bunch, Marvel decided to go all out crazy on their new film and exploit the ludicrous and wonderfully bizarre worlds of the comics. Directed by Taika Waititi, Thor: Ragnarok develops the psychedelia of Doctor Strange and the humour of Guardians of the Galaxy to come up with a whole new beast, and all for the better. With fantastic effects, surreal and improvised humour, plus a great cast, we look into the success of Marvel's latest offering. Starring Chris Hemsworth, Cate Blanchett, Tom Hiddleston, Tessa Thompson and Mark Ruffalo.
