SPOILERS. There are basically two stories going on here. There is the modern story of the family who moves into this home and finds Cassandra the robot.. and then the flashback in time showing Cassandraโs original story before she was a robot. Cassandraโs story was very interesting and really couldโve been its own movie. The modern story was very frustrating and illogical. As many people already stated, it was frustrating how the husband just automatically believed this robot over his wife, who by all accounts has no history of mental illness and is an intelligent and rational woman. Another thing that bothered me was that they moved into a home that has been empty since the 1970s, and yet they never even looked under the bed?? They didnโt know there were GUNS under the bed?! But the most ridiculous part of all was when the robot takes them โhostageโโฆ. She rolls around like a vacuum cleaner; all the father had to do was to kick her over to the ground and stomp on her, then even if she could turn the oven on and lock the doors, he couldโve picked up a chair and smashed the window and they couldโve escaped. He was so scared of her & helpless. It was irritating.
