all in all, its a nice movie (i do like tom hanks' Castaway and the idea of how isolation/being alone affects human psychology)...in this film, the "last man on earth" feel is there...for me, the only set back is the darkseeker characters...its too computer generated...they should do it like 28 days later (i mean the zombies are fast and rage fueled)...nice touch on the scene where will smith has to kill "sam the dog"...and no complaint on the ending...

i think that's one of the mutation caused by the virus once people got infected...muscle tissues expanded and they became stronger (and can jump higher)...other than sensitivity to uv ray, extreme aggression, lost of human senses, hunger for fresh blood/meat, etc...

hehehe...that one wasn't the virus' fault...it was the cgi image fault...the 3d image artist was too lazy to make the female darkseeker's anatomy as detail as it should be...

i think even if they're going to make a sequel, it won't be about will smith bcoz he's dead...maybe they'll do it like 28 days later & 28 weeks later...i mean it's a whole new storyline (maybe 10 years later) where the virus mutated and immune to the antidote...it's a new virus and deadlier...and the infected have no weaknesses...
