OK this film has virtually no budget for a sci-fi movie and no real stars to speak of other than Peter 'Robocop' Weller but that doesn't matter because what it does have is a good story well told. It's a shame that bigger budget sci-fi productions never seem to remember that sci-fi should be have an interesting premise and not just throw a few explosions at the screen every few minutes.
What is on offer in Screamers is a solidly entertaining 1hr 40mins of sci fi fun, reasonable acting and a great story based on a Phillip K Dick short. The main idea of screamers is a very scary one a war that had been taken over by machines that fight on our behalf a war that can't be stopped.
For sci-fi fans this is a must see, for everyone else it's still solidly entertaining 7/10
