The moon IO might be something special. The movie IO is not.
Life on Earth is over; the climate won’t allow it. So, humans have left to colonize IO. Sam remains, studying and experimenting, convinced that life will find a way. It’s a lonely existence. After several surprises, she must decide whether her research is worth her life.
This movie starts slow and never picks up. It tries to walk a balance beam between existential depression and human connection, but it falls smack onto one side of the floor.
