Yes, Dark Fate will almost certainly be the lowest grossing of the Terminator movies, but it has almost nothing to do with your anti-(whatever you're angry about this time) stance. Try to think a little more objectively about it.
The three movies before this ranged from not very good to terrible. At this point, it has been nearly 30 years since there has been a good Terminator movie. It holds no cache with younger audience and there is only so many times that older fans will get burned before tuning out. Even when the movie is better than it's predecessors, as this one was. Given the franchise history, this movie had to be more than better than the previous movies to get people to come out again. It had to be great. And, frankly, it was just fine. Not great, not terrible. Worth seeing, but maybe not in theaters.
