Harry Potter and the Deathly Hallows Pt1

The tone's been set for this series - every instalment has to be darker and more adult than the last, the stakes higher, the dangers more profound. And on that front, this, the seventh, delivers. It does feel like half a film, despite its not inconsiderable length, but doesn't seem a cheat in the context of the series as a whole, which has turned out to be quite an achievement.
