We've just watched 'I am Legend' on the DVD. It was scary (I'm not a fan of scary films - Shrek, Love Actually and the Railway Children are more my type of thing).I vaguely remember an old Charlton Heston film called, I think, 'The Andromeda Strain', this film appeared to be a remake of that.
In common with many post apocalyptic films of its type, it had a common theme, that he end of civilisation will be caused by a virus caused by genetic experimentation. It may seem fanciful, but to me it would appear to be a salutary lesson in being cautious with allowing genetic experimentation.
