*grins* I have on occasion come out of films and then complained for hours about the bad half assed handwaving 'science'. It seems horribly hypocritical not to try my best with something I'm writing. (Especially as I am in a related field).

The science won't be perfect, it doesn't matter how much you tamper with someone's genetics it won't give them the ability to change the weather or shoot lasers from their eyes, (though you could probably theoretically increase healing rates, give them wings or increase their speed and agility with enough changes). I can work with what is real though and extrapolate.
