Video game movies have always been a tricky beast to tame. None of them could ever really deliver on the promises they made because they often strayed too far off the original material.
Here, a new low has arrived (until Bloodrayne 2 and 3 came by). Even if Rayne is a Damphir (a half human half vampire creature), she shows none of the talents or wisdom, thanks to a witless script and very boring conversations between characters who can do nothing else but argue instead of looking at the camera and say "want your money back?"
Uwe Boll flicks (not movies, let alone films) are pretentious, boasting an empty chest and barking without any bite. They show no substance and very little style, and once more, a video game that had "some" promises is left bleeding to death.
If you really care about special features, your best bet is to look for interviews with the man himself, who seems to like to complain why people hate him (pick a wild guess!) and answers his phone during a commentary track (I don't remember if it's this particular title). There is a meagre making-of where everyone goes EPK and says how Boll managed something and what a visionary he is.
With this much (or this less) meat to hold on to, your hopes better be very low for anything Uwe Boll related. His big-budget days are looking like they're behind him for good... all that is needed is for the man to find a true artistic voice, but there's nothing suggesting that will happen.
