Wow this movie was really nice! It's a "zombie" (or infected type of movie that doesn't focus much on the monsters, still, it was able to capture my attention because of the interesting dialogues, the tension that's slowly building up as the infection spreads to the population, while the protagonists are trapped in their radio station.
I also liked the redhead lady, then I learned she was Patricia Tallman, the same girl who played Barbara in that 90s remake of Night of The Living Dead! The main guy in this movie is Bob Moseley, who was the actor who played as her brother in that NOTLD remake lol

Wow, I never knew "old" ladies can still look that attractive!
Anyway, I think this movie will appeal to viewers not because of the action, but because of the tension that builds which makes you feel you're somehow part of it.
Thanks for this movie, I really enjoyed it!
