Following the reappearance of evil Lord Voldemort, there is a general murmur of fear running throughout the world of Potter. The newspapers are desperately claiming that the dark lord's second coming is just a rumour and they're trying to smear the name of Harry and Professor Dumbledore in the process.
The Ministry of Magic is certainly against Harry and his headmaster, and so they dispatch one of their own to Hogwarts to impose some serious restrictions on what can and can't be taught. Some of the pupils begin to grow worried that they won't be able to defend themselves should they come face to face with Voldemort again, and so it falls to Harry to train his own army of school kids.
For once, in a Harry Potter film, we actually get to see some cool magic. Not only is much of the film devoted to Harry and chums honing their skills, but we finally get to see an awesome battle between multiple wizards, with all kinds of different spells being used. Which really begs the question, why weren't the previous four films packed full of this stuff? To my mind it's like watching the Lord of the Rings films without any of the swordfights – they'd still be quite good films, but they'd be much worse off.
Director David Yates (who?) has stuck to the dark style of the last couple of Potter films and produced plenty of exciting moments and good performances from the cast. To be honest, I don't know what else to say about this film, except that it is probably my favourite Harry Potter film so far. These Potter films still have plenty of potential to be much better than they are, and while this one is better than the previous efforts, it is only just peeking over the top its predecessors instead of standing head and shoulders above them.
