Disc one contains the film itself. To sum it up as average would probabl be fair - ok, but nothing special. Nice details on the historical front along with decent action scene are spoilt a little by parts of the screenplay, in particular a fairly major detail of the ending which is impossible to describe without giving away major spoilers.
Disc two lets the package down completely. There's a lot of volume, with 10-12 different additional documentaries and things about the making of the film and its historical context, but sadly most of them descent into self-congratulatory nonsense, often describing how much of a pleasure it was to work with Tom Cruise rather than saying anything substantial about the film itself - to the extent that discussion of the action scenes talks in depth about how Tom was determined to do his own scenes wherever possible. Drivel.
