In case you weren’t aware, the title stands for the International Space Station. In this sci-fi thriller it’s occupied by 3 Americans and 3 Russians working in scientific harmony until something horrible happens back on Earth. Both sides are instructed to take control of the station no matter what. This sets up the tension, which starts to develop pretty well. However, halfway thru things start to be more about paranoia and intense discussion and less about thrills. There are some apprehensive moments, but ultimately it doesn’t live up to its menacing potential.
