User Reviews

Above average Sci Fi quasi Living Dead drama.
19 February 2006 | by (United States) – See all my reviews

I remember seeing this 20 yrs ago and having a very favorable impression, but the recent copy I bought and viewed this week showed both better and worse aspects, different from what I recalled. Anyway, the story is quite catching and most of the acting is above average, thanks to a good ensemble cast of quality folks. Very well done art/set design makes up for rather standard plot direction, with some nicely eerie moments. There's well written, believable dialog interspersed with silly, and well developed characters interspersed with stereotypes. So it's a mishmash but a good one. Would have been nice to see a more believable military response to the viral outbreak, but the budget must have only been enough for a small crew of national guard type soldiers rather than a more believable crack platoon outfit that would have been all over the locals, and sent them packing. Definitely a good half of a double feature with Endangered Species, or Andromeda Strain.
