If you're into a mixture of horror/thriller/mystery/drama with a strong ecological message, then you'll probably dig this British movie. I personally prefer this kind of stuff a bit more grotesque & entertaining, like "Prophecy" (1979) for instance. Though that one was more like a monster-movie, "Doomwatch" feels more like an early George Romero film (a bit like "The Crazies", perhaps). Still, if you know its premise, then there is a lot less to enjoy when you watch "Doomwatch". The protagonist is investigating and figuring things out, but the viewer already knows what's going on. So that was one of the reasons I didn't enjoy it that much. And indeed, the movie felt like padding a bit in certain places. Still, it is a decent enough made film, worth a watch. I'm more interested in checking out the TV-series now.
