I have seen this movie a couple of times on DVD and whilst it is based on fact, there is an awful lot of poetic license taken with this film. That aside, this film is actually very good and has a great mix of heart-warming love, friendship and unity coupled with shed-loads of dramatic action, explosions and blazing guns.
Quality wise, the BD version of this film is jaw-dropping. Colour and detail are unrivalled and the soundtrack is simply awsome. DD is fantastic, DTS incredible.
You might not be a fan of this sort of movie but if you want to see what your HD system and surround sound set-up can do, get this movie on BD.
