The movie was ok, though I think most people are scared of Ai because of movies like this.

I would have liked to know why she went crazy. Instead of the first scene they should have shown what happened. Did the programmer code the house like this on purpose? Did guest treat it wrong and it decided to kill all humans that entered? I would have liked to know.

Lastly Hanna was smart enough to code the malware and to out smart the Ai but she brings a Bluetooth device in the car? Come on, worst ending they could have had. How about the Ai figures out how to make a construct that can leave the building and they go to the cops and the build is shut down but in part two the cops are on the trail of a serial killer but they don't know it's the Ai. The Ai doesn't kill Hanna because she respects her but maybe someone who got away told the cops that it was some weird shape shifter. They think it's an alien and Hanna hears about it on the news and goes to the cops or fbi and tells them what it is and helps bring it down for good.
