Terrible title but decent movie
The handful of IMDB reviews I read seemed to be disappointed that this wasn't some action packed Terminator-ish movie... which is exactly the reason I enjoyed it. It's really a drama with some action sequences here and there.
I don't know why they settled on such a terrible title which may have contributed to the problem.
It's similar to what I remember of The Walking Dead... mostly about the relationships between various human factions with the periodic appearance by menacing androids for some low-key action sequences.
The androids are not particularly destructive. They are somewhat more robust than humans but not much. That's because they were previously used for domestic labour. They're not hardened for military applications so succumb relatively easily to bullets and blades. However, they are quick to learn about human behavious and emotions and are starting to use that to their advantage.
The only issue I had with believability is Chloe Moretz' super-human pregnant wife. Despite being very large with a baby and on the cusp of giving birth, she does a lot of running, falling and exerting herself physically, crying out periodically to remind us that she's in a lot of pain as she does the super-woman stuff.
The ending is a gut punch, but I won't say more than that.
