Well... I will first give credit where credit is due. I will admit that despite the many flaws to be found, I was never bored once during my viewing experience. And I will also admit that Halle Berry gives it her all, and certainly deserves an "A" for her great effort. Unfortunately, Berry is often required to spout dialogue (when no one else is around) that feels quite contrived and makes you think that the filmmakers thought the audience would be too stupid to figure out what her character was thinking and feeling if she was silent. A bigger problem is that there many moments where her character does some really stupid things that just extend the situation instead of finishing things much sooner had her character had some basic smartness. For that matter, the bad guys (and also some other characters) do their part to act stupid enough so that they stretch out the narrative as well. Had the movie's characters been of reasonable intelligence, we might possibly have had something here. But as it is, the movie is not that much better than silently watching a blank wall for 95 minutes.
