So I've just come back from watching Thor Ragnarok and I can tell you the film is brilliant! Nothing particularly spec worthy that hasn't already been mentioned. Kat Blanchett is brilliant as Hela as is Goldblum as the Grandmaster of Sakar.
Its got a different tone from the other Thor films, there's obviously a lot more humour. The chemistry between Thor and Hulk is very funny and the character Korg played by director Taika Waititi is hilarious!
I'm not going to give any spoilers away but just go and watch it ! Its now one of my favourite MCU films and has definitely boosted a Thor franchise that probably had the weakest films in the MCU.
