Well, Terminator: Dark Fate was very Terminator-y. Kinda felt like a huge rehash of T2. Even T3 was more innovative in terms of storyline. It was an ok way to spend a couple of hours but definitely nothing new.
Effectively it's the same plot again, except more contrived. A new completely unrelated AI just happens to end up like Skynet and make almost identical terminators, and send one back in time to do the whole "kill resistance leader" thing, while humans from this future also send back in time an agent to stop the other one. None of the entities are even aware of the aborted Skynet timeline. I mean, what are the actual odds of this?
It's also cashing in on the big "girl power remake" vibe that's been going on these days, and passed off as feminism, when it's really just a flimsy excuse to squeeze a little more blood out of dead franchises. I mean, this is just a gimmick at this point. At least have some new plot where any of those differences even matter: if you can just gender-flip everyone back to male without changing any of the plot-points then it's not really a female-centric story, it's just a standard Dude Action Movie but with girls cast in it.
It's is bombing out at the box office btw. i think the thinking is that putting female characters as the lead characters in high-budget action / effects movies (ones where traditionally, the audience is about 90% male) will double the potential audience. But this is flawed thinking. Most women I've heard talking about such things tend to talk about the cute male stars of such movies. It's pretty much the only draw for a lot of them to even bother. Are they going to see a Mark Wahlberg movie, or the same movie with Angelina Jolie or Scarlett Johanssen in it instead? Most women will see the Mark Wahlberg version.
Battle Angel Alita was cheaper to make and did better at the box office, despite the relative lack of brand-recognition. So it's more likely to see another Alita movie than another Terminator movie in the near to medium future. Which is honestly a relief. Terminator really isn't that suited to being a long-running series of movies, due to the entire premise of the movies.
