Great movie! Decent amount of action with plenty of thrilling drama.
While some ‘christens’ were and still are triggered by this movie, the overiding message this movie deals with is personal acountability and responsibility for ones actions and behavior.
As for realism goes, I personally have witnessed basically this exact behavior sans magical powers.
A decent zombie flick, not quite good enough to be mediocre, but still watchable.
Obviously a low budget film, although it does not have the feel of one, it suffers only from backward leaps in logic, continuity errors, a need of more action and the over used hollywood trope of last minute rescue.
