ok this film have virtually no budget for a sci fi movie and no real star to speak of other than peter robocop weller but that doesn not matter because what it do have be a good story well told . it a shame that big budget sci fi production never seem to remember that sci fi should be have an interesting premise and not just throw a few explosion at the screen every few minute . what be on offer in screamer be a solidly entertaining 1hr 40mins of sci fi fun and reasonable acting and a great story base on a phillip k dick short . the main idea of screamer be a very scary one a war that have be take over by machine that fight on our behalf a war that can not be stop . for sci fi fan this be a must see and for everyone else it still solidly entertaining positive .
