Kate - completely superfluous character
After watching this movie I was bewildered by the inclusion of Kate's character and suspect producer meddling to be the cause. I have no problem with her acting - she is a perfectly fine actor and a beautiful too. The problem is, her character adds absolutely nothing to film and actually ruins it to a great extent. I get the definite sense that the script didn't originally include her and she was quickly added in the final hour at the insistence of money hungry producers requiring a more bankable teen-friendly picture.
MAJOR PLOT SPOILERS AHEAD...
In the scene where Bobby is ordered out of the car, how much more impact would there have been if Bobby was the only girl in the car with them? Just the two brothers left alone.
Similarly, when Danny shoots his brother, the impact is lessened by the presence of Kate, her only justification for being there seeming to give him the gun to do the deed.
When she washes herself at the well it seems a blatant attempt at a Michael Bay style iconic shot and I'd bet good money that the Blu-ray/DVD will include that shot on the back when it's given a release.
Kate virtually has no screen presence throughout and the only time anyone acknowledges her is when they refer to her as Danny's 'girlfriend' and are then vaguely informed that she is in fact not his girlfriend. We are never informed how any of them know the girl.
Most crucially, the end scene where Danny reaches the beach and says "We made it" is pretty much neutred by the fact that she's there with him. Imagine, if he was alone and said "We made it". Now that would've been a tear-jerker and a half. No girl, no hope for recreation. Just one guy on a beach with his memories. Not surprisingly, Kate then conveniently disappears leaving Danny standing alone in the final shot. It's not like anyone can fight the case that she never really existed in the first place and was some kind of ghost/projection because as mentioned his brother actually acknowledged her in that one scene.
To be fair, I think this film was pretty damn good and a refreshing break from all the zombie clones out there but wonder how great this film might have been had Kate been excised from the whole thing.
