Kill Command – available on Netflix now:

A group of soldiers is sent to an island for a routine training exercise to find out how they do against specially designed war robots. One of the robot creators is sent along to evaluate the training. None of them were expecting to be ambushed by autonomous killer robots

I found this one surprisingly entertaining and better than expected. The acting was decent as well as the special effects. The leader killer robot was especially intimidating. The story of killer robots is nothing new but the action and special effects make this one worth watching.
