If you loved Zoo, try Resident Evil 4D Executer
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theysit in Animation / Horror territory. If that's the register that drew you to Zoo, the second film will land in a comparable space — through a different lens.
What Resident Evil 4D Executer is
Raccoon City, late autumn. The whine of a distant chainsaw. Hired guns descend, hunting a scientist and her forbidden data. The Umbrella Corporation's tentacles reach deep. Another quick hit of bio-horror, direct from the DVD era.
