I always love to see indie filmmakers take a crack at science fiction on a limited budget. Dead Space is as impressive of an attempt as I've seen in the live-action department. Primarily for what they did in production design and practical effects. Gotta love that suit and helmet. The production team was also smart enough not to overreach.
I love Dead Space even more because Eric Zaragoza, who leads the crew at Z Pictures, spent four years in the Marine Corps before heading to film school.
