Half an incredible film.

Rating: 5/10 (14 December 2007)

Do yourself a favor. The instant the "Anna" character appears, leave the theatre. At that point you will have experienced a remarkably potent, emotionally devastating film.
After that, the movie takes such a stunning nosedive that it's almost impossible to believe that's how it was originally meant to end. Indeed, there are even scenes in the trailer that suggest a completely different (and vastly superior) direction to the film, and there are plot elements through the film up until this point that corroborate that direction.
And then Anna shows up. And it all goes to hell. Suddenly there are bright lights, explosions, deus ex machina for miles...the movie is completely destroyed. If you hated the ending of "28 Days Later," try to imagine that instead of the ending being five minutes of disappointment, it's the entire third act.
I really hope we get to see how this movie was supposed to end at some point, because I can't fathom the original script just randomly sucking as much as this one did at the end.
