Interesting, i've always thought that the early stages of an outbreak, when zombie attacks are mistaken for homicides was a concept with untapped potential.
Especially if there's an added mystery to solve. Discovering what's going on and why, brings another layer to the usual zombie fiction.
And Resident Evil is well suited for this kinda thing, what with all the corporate conspiracy stuff. Although it would probably work best as a mini-series, wouldn't want it to drag out too long.
