Yeah, I am Legend was pretty good. I like how the writer tied in everything about the butterfly but uhh... at the end, I didnt understand how they could distribute a vial of blood to everyone. How did they recreate it?
But then I asked my cousin and I forgot that you can do it with uhh I think it was called the process of transformation where the bacteria will adopt a gene into its genetic code if it is exposed to it.
I guess you can do that to replicate the blood? But I mean blood by bacteria is kinda weird, isn't it? haha
