Query: Good dvd, mediocre movie

Harry Potter and the Sorcerer's Stone the movie was really bad compared to the book. But assuming that you haven't read the book this movie is really injoyable, not worth owning though. The special features on the other hand are really fun, you get to explore hogwarts in a 3-D journey as you collect items to open new levels, you can play games and meet the characters in the movie. The 4 stars refers to the dvd, the movie, however, only deserves 3.
