Obviously they had to cut some stuff to give a reasonable film length, and they managed to do it well.
Speaking of barrows, I'm don't recall (though I don't have the books here) the burning of The Barrow from the book. It's certainly a very dramatic moment, though I'm not quite sure what was going on with it. Perhaps the director just thought the film needed more fire?
I do like the sequence with Draco experimenting with the Vanishing Cabinet, learning how to use it. In the book it's simply a mystical pair of wardrobes that just work automagically (if you'll pardon the expression), while in the film he has to try again and again to get it to transport the object unscathed.
The final sequence was excellently done. It's an interesting change to make: while in the book Harry is invisible and paralysed, here he's hiding the old-fashioned way. He even gets spotted by Snape, and I'm surprised that Harry doesn't try to stop him. And there's the simple "Snape... please..." from Dumbledore at the end - having read Deathly Hallows, it holds a very different meaning to what it would do normally. A very good bit of film.
The soundtrack was excellent as well, although annoying the cinema did the usual thing of turning the volume up too high. I hate it when the sound starts distorting because some fool thinks louder is always better.
Anyway, time to watch the Top Gear from earlier. I love having a TV card in my computer.
