I have just wasted 90 minutes of my life watching this rubbish.
Its sheer laziness on the part of film makers to provide a good build up then just end the movie without any kind of decent ending.
When the credits rolled there was still 11 minutes left and I thought perhaps the producers were trying to be sneaky and will add something decent after the titles - but it was not to be- there really was only 73 minutes of film before 11 minutes of closing credits appeared - obviously to pad out the meagre running time.
I'd forget the Bluray.
Due to the style of the film and the hand held camera throughout you dont really get the benefit of the HD quality that you get with other Blurays.
The extras are the usual puff pieces .
I'm glad I rented it and didnt buy it.
As a fan of Alias and MI3 JJ Abrams has disappointed me on this one
