An almost completely different animal than its predecessor. A lot of unnerving imagery with a slightly more disturbing story make for a much better sequel. Not much in the way of monsters but by the time they get loose its a hell of a good time. Not too much of a Hammer sci-fi fan, but Quatermass 2 is definitely an exception.
A surpringly taut and chilling second entry in Hammer's film versions with vivid locations and (sadly) quite believable situations. It says more about human frailty than alien invasions and is all the more frightening as a result.
Val Guest was such a master of this material. The sequel to the original. Enjoy this a lot, the moonbase location and the rare performance of Sidney James in a serious role make this a stand out classic.
