My opinion, they would be great for any thriller lol. Literary, I s**t myself when I first fought the Flood seven years ago . The way they "live" is just creepy. Coming like 30 of them and bringing back to life dead while hearing the poor victims scream in pain and try to stop the infestation progress, with no luck. And next, they transform with their head have no meaning, and have a large claw to wipe out other survivors...
WHAT THE HECK DID I JUST SAY
