I think you have to go all the way back to Terminator 2 in the early 90's for the last good movie of this franchise.
So fans were looking forward to the new 6th installment because it was going to take up from that movie and ignore all the rubbish movies since - and James Cameron is going to produce it.
So they seem to have had high hopes UNTIL the first kinda poster teaser for the movie came out in recent days:

I'm all for empowerment of women and all that stuff but I agree with the backlash here. I don't go to the cinema for politics or to have this SJW stuff forced down my throat. I just want to see hopefully a good movie with great characters (male and female) and leave that sh!t at the door.
The thing is it's so in your face - the message. I don't see any need for it.
Everyone is in favor of more women empowerment in movies as it is. Or at least I don't see anyone objecting.
Anyway this is far from the first franchise likely to suffer. The remake of 'Ghostbusters' in 2016 to an all female main cast was more of the same stuff with Hollywood trying to force it's SJW ideals on the audience. Of course it flopped - I don't know maybe because the original movies fan base was mostly
men!?
