Check out my list of this year's best dvds. Then we can argue. It's part of the fun. Are the best DVDs all about the quality of the movie itself? Or is it more about the wow factor in image and sound that lets your home-theater system rock the house? Or is it those rare bonus features that go beyond hype to actually reveal something about how movies are made? You hardly ever get all three in one package, but here are the twenty-five DVDs that come the closest.

The best of the three Potter films to date -- thanks to the dark magic of director Alfonso Cuaron -- is also the best DVD. The first two films were slogs due to the candy-bright view of director Chris Columbus. Cuaron works in the shadows, where mystery, sex and trauma do their mischief. The crisp transfer catches what goes bump in the night.

Extras: There are interactive challenges for the kids. But the interview with author J.K. Rowling is the no-bull surprise. Killer Scene: It won't be just kids who get nightmares from the attack of the killer tree. And poor Harry (Daniel Radcliffe), who thinks a prisoner (Gary Oldman) is the key to his parents' murder, is in for a shock from soul-sucking creatures called Dementors.
