terrible acting,dumb plot

Was predictable, but Halle Berry played the role very well. Movie kept me on the edge of my seat. Parts were sketchy, with no rationale about why the bad guys were doing things. (e.g. why take her in her car and then try to kill her, when they could have killed her when she stopped.) And what happened to the dog that was viciously trying to attack...did it get shot? It just vanished.

Didn't keep my attention. Too contrived.

The movie was not believable, though at times did hold my interestst.
