Josh Brolin and everyone involved (including Megan Fox and Michael Fassbender of all people) waste what few or loads of talent they have in this mess of a production that, at 80 or so minutes manages to make no sense, no feeling or no cohesiveness whatsoever. Give yourself a favor and avoid this at all cost.
Picture and audio may be well deserving of your attention, since detail is quite impressive and sound is immersive enough, but still, that doesn't account for the atrociousness you're about to embark.
Special features wise, it's one lackluster blu-ray so once more, it covers the generic ground (where the character comes from, some of the movie's supposed improvements, etc.) but never with any depth.
Once again, stay far away from this. I could have given it no star at all, and at $5, it's not even worth picking up except for watching Megan Fox acting even less in a parody of Sergio Leone's movies combined with Constantine's visuals without either one's talent or ambition. Do not even rent, unless you're absolutely sure.
