Watched all of it, and it's terrible, like everyone else has said. I'll go through a couple of bullet points to highlight the most egregious things (will contain spoilers):

1. As everyone pointed out, the first episode sees the main wench out-dodging and out-manoeuvering the Terminator with ease after he just mowed down a hundred armed men. She's doing acrobatics and dodging his bullets, which is pretty dumb because if she were more tactical or had help from a team it could have been more grounded and believable, but it was typical anime girlboss plot-armour that she even survived that barrage of hail fire.

2. Everyone and their mum seems to be able to build time machines in the future. Skynet has one. The rebels have their own time machine. And somehow a random black guy managed to capture a terminator and build his own time machine in his dorm. Not even kidding.

3. The action scenes are extremely boring because they're too over-the-top and Eiko is depicted as invincible throughout most of it, just until the plot calls for her to conveniently be injured. The scene where she's holding the terminator and he's repeatedly axe-handle smashing her back and she just tanks the shots is ridiculous. The only almost decent action scene is in the police station, where they at least had some of the cops act sort of competent for a little while. But that was short-lived.

4. The whole thing about Marcus creating an AI out of Skynet's CPU to combat Skynet is ridiculous. And the low-brow philosophical debate about the AI achieving consciousness was groan-inducing and just outright bad. The AI deciding it "wants to do better" in the end by being more than just a destructive tool was ridiculous. The more realistic scenario would have been like Ex Machina where the machine recognises its most prominent course of action leading to the highest potential success rate and going that route. That made sense from a machine's perspective because machines don't feel. Having an AI have an emotional epiphany was just beyond words, and obviously just horrible writing.

5. The female terminator that Marcus brought back with him that somehow didn't know it was a terminator was outright stupid. And it also made zero sense how it had a John Wick mode built in under certain threats of violence. Where did they get any of this from? The fact she was somehow acrobatic and did martial arts just made no sense -- she was still running the same logic as the main antagonist terminator, so why was she different?

There were a ton of other logical inconsistencies and huge plot holes, but I can't be bother to go over them again. The whole thing was just dumb.
