Zoe Kravitz pretty much knocks it out of the park as a PTSD suffering, live action "Alexa" algorithm who overhears something through the titular "Kimi" device, not intended for non psychopathic "not with the cool folks" ears, and then makes the naïve mistake of thinking that her supervisors or their superiors would want to help, as the default response in most tech corporations is to either cover up anything nefarious, and or destroy anyone uncovering anything nefarious, unless it makes the company look SO horrible that they are forced to deal with it in a non homicidal manner, to get ahead of the backlash.

The setup is paced to allow you to somewhat understand the extent of her character, Angela Childs fears and phobias, although the explanation for them is glossed over with the standard "I was assaulted, and the police put me on trial instead of my attacker", rather than going into any in depth explanation. Yet, she still appears to have a completely intact and fully functioning libido, as evidenced by her apparently frequent "booty calls" with her would be paramour, Terry Hughes, who lives in the loft across the street, in a neighborhood where no one appears to be able to afford curtains or blinds, and are content to peruse and ogle each other, and not feel the least bit creeped out about it. But perhaps that's just me. Modern times, I guess...

Things pick up when she FINALLY realizes that the good guys are the bad guys, the Calvary ain't coming, and she's going to have to save herself, although, for a supposedly tech savvy person, she makes a few rookie mistakes such as not turning off her phone, removing the battery and SIM card, or disposing of it and using a burner phone if all else fails. Also, going straight to the folks her supervisors were hesitant to call in the first place, AFTER she realizes they mean her harm rather than helping her, but then again, it does make her more sympathetic in that she's not an omnipotent savant, but a very smart, somewhat damaged person simply trying to do the right thing.

The action ratchets up in the third act as someone we had questions about in the first two acts (...yes @JimDarko, that is INDEED Kevin McCallister's older brother "Buzz") who turns up seemingly out of nowhere to try to help. Things get pretty sketchy when Angela has the opportunity to turn the tables on the baddies with the help of her electronic helper / nemesis, and let's just say, she like "Lethal Weapon's" Murtaugh, "nails em' all".

Hmmmm, who knew that justifiable homicide was the cure for PTSD and Agoraphobia?

I enjoyed it, you might too, and like Forrest Gump, "That is all I have to say about that!!"...
