After the terrible events at the end of Goblet of Fire, Harry thinks that everyone in the wizarding world will believe that Voldemort is back. However, the Ministry of Magic are keen to stem any rumours, and suggest that Harry and Dumbledore are lying because Dumbledore is after the job of Minister.
The Daily Prophet newspaper joins in this denial, ensuring that Harry has a miserable time back at Hogwarts, as fellow students accuse Harry of scaremongering for his own gain. That is, until the Ministry favourite Dolores Umbridge joins as Defence Against the Dark Arts teacher. Umbridge is cruel, using torture to control the pupils, so when she deposes Dumbledore and starts to rule Hogwarts with a rod of iron, the pupils group together to form Dumbledore’s Army and begin training themselves to fight dark forces.
It’s not a bad film, but it feels very bereft of decent storyline after its two immediate predecessors. There is a lack of action, and is a sprawling, over-long movie, which doesn’t advance the Harry Potter tale on a great deal.
