I'm not sure how familiar people are with the blockbuster
Terminator franchise.
It began with a 1984 cyberpunk sci-fi horror movie
The Terminator. This dealt with artificial intelligence, time travel, and more than a little bit of the
Frankenstein folly of creating what may destroy us.
The second film was more of a straight-up action flick, following up with Sarah Connor, the protagonist of the first film, and her young teenage son John. It doesn't go into her intervening years much, when she fled to Mexico for "safety" among drug cartels where her treatment there turned her from innocent to a dangerous, feral man hater. This culminated in a belief that one of the Terminator machines would be a better father to her son than any man.
From there the timeline splits (the time travel factor makes this more plausible since it already brought up parallel universe ideas). Most of those movies are enjoyable, but a little dicey in various ways. They never really lived up to the first two.
However one of the post-T2 splits was the short-lived TV series
Terminator: The Sarah Connor Chronicles from 2008.

Here Sarah has worked through a lot and even begun to settle down with a new partner. This is a strong and stable guy, John likes him, and things are looking very good for them.
But the AI from the beginning of the franchise isn't done with Sarah. She made herself its primary threat in every timeline which had prompted it to send back Terminators through time in the first place, setting up the cycle.
Things start slow and then get crazy. She resumes her mission to sniff out and extinguish the developing AI and those responsible in her time. Along the way many things are explored including religious aspects of it all for some characters.
Without giving too much away, there are unexpected developments, such as a future
split in AI factions. One faction might actually want a productive truce and partnership with humanity. Another tangent is more elaboration on the creation of Terminators with a cooperative purpose (as we saw in the 2nd movie
T2).
There is a lot of exploration of humanity here and parts of the story have a lot of heart. There is also plenty of food for thought, eeriness, and outright horrific stuff here.
It's a favorite. I have it on DVD. I don't think it is free to stream anywhere right now But Amazon and YouTube are offering it for a price.
