Nice try, but doesn't quite work.

Rating: 6/10 (7 January 2008)

Here we have more of a re-envisagement of the 1971 'The Omega Man' than the book 'I Am Legend'.
The film sets up the scene nicely but alas quickly falls into typical Hollywood habits resulting in somewhat of a dumbed down script/film.
*SPOILERS*
1) Why are the infected made mindless monsters by the disease? The virus reduces their brain power but for some reason gives them superhuman strength, realigns their jaw bones (so they have bigger mouths & can shriek like Godzilla) and generally makes them just look rather unappealing. The over-the-top CGI rendering of them looks just like that, CGI rendering, which really does not help the audience 'bind' with the film.
2) Why does Neville see fit to try and remove his scent from the stairs to his house? Surely if the infected follow his trail to the path at the bottom of the stairs they might just by sheer chance try the door at the top of the stairs?
3) Why is it necessary to charge after deer in a sports car (other for some product placement)? Surely just a good shot (or machine gun) would suffice?
4) Given all the (explosive) preparations Neville has made to defend his house, why not just use plenty of nice big UV lamps?
5) Given the clear intelligence of the 'lead infected'  who sets up a VERY elaborate/complicated trap, why doesn't he just pelt Neville with rocks while Neville attempts to crawl away from the trap? Or better still just find an old gun and shoot Neville?
6) His wife shows 'positive' on the infection test, and then on a second attempt proves 'clear'. And the other survivors turn up just in time to (somehow) save him. Oh common writers! Why sink to this sort of stuff!
In short, the film just bends too far away from 'common sense' and 'believability' for the sake of contrived sequences and effects. I would have preferred to spend far more time with Neville and discover more about the creatures, but unfortunately the second half/third of the film seems to rush through not leaving much time for this.
Worse of all, we lose the entire (clever) premise of the book (which the film names itself after) - Neville is now the odd-one-out. He is the bogeyman, the monster which comes out in the day, hunts them down, and kills them
With a better, more sensible script, this could have been a great film, but instead we end up with basically average Hollywood action fare.
6/10 - Shame it wasn't more like 'The Omega Man' film, or the 'I Am Legend' book.
