Factual error: Detective Beck is at the morgue. A man comes by and make an incision in the detective's arm. Blood flows freely from the cut. That is not possible. Livor mortis would pool the blood in the lowest parts of the body after around six hours of being dead. And this cadaver has been dead much longer than that.
Factual error: Detective Beck's daughter states that she had not seen her father for several years. That he lived as a hermit and did not let her in. Then why when she goes with the good alien to where her father used to live, she has the key to get in?
