I had a lot of fun with this one - they did a lot on the budget they had, and it sells well. The setting of the elevator gives everything a really claustrophobic and tense feeling. It was easy to get hooked on the struggles of the characters - they were all really likeable and well-acted. I especially liked Jacqi, the knife-wielding teen. She was badass, and I especially liked her dynamic with Mason, the criminal with a heart o' gold. Overall, a really solid, fun little zombie flick - definitely worth watching!
