A little bit about the product: It has both Japanese Audio and English Dubbed for those who prefer the dub. The extra features such as the picture dramas are available both in dub and sub, audio commentary is also very good and offers some fun trivia knowledge about the people involved in making the series. For those who have lived for subs, the DVD box set is great. Only thing probably missing is maybe a sheet that tells you which episodes are on which discs. (For people that have watched this series and want to skip the funny episodes it might have been good.)
Overall verdict of Box set: Amazing. It's everything you want in one place.
At the price that this is at, it's a bargain. 25 episodes and extra features (openings, endings, picture dramas, etc) would cost more if you buy the volumes separately.
The series itself: Great series, one that you can definately watch again and again. This series has some of the biggest plot twists ever and will probably leave you watching episode after episode until you finish the whole series in one go.
Overall, it is definitely an 'Anime Legend' and worth watching.
