Not gonna lie, I disagree with the assessment of this movie. I think it's less of a reboot and more of an altered timeline (which, given the temporal arms race between humans and Skynet, is pretty likely), and held to a lot of the canon lore that might not have made it into the extended cut of the movie, but did come up in the novel and comics. Cameron set a high bar, and this didn't quite clear it. Still a fun movie, even if parts were sort of "meh."

And one that is begging to be riffed...the negative reviews in this comment thread alone read like scripts for a rifftrax! Like the movie or hate it, it's ground waiting to be farmed.

Additional reasons:
1) "Not Linda Hamilton" and "Not Michael Biehn." Based on the timeframes, you can understand why most of the original cast wouldn't work, not like it did in Dark Fate.

2) Get ready for Game of Terminators! Emilia Clarke takes up the role of Sarah Connor. IMHO she captures the personality of the resistance fighter. But you just know the Game of Thrones jokes are just waiting...

3) More than one Arnold in the same shot.

4) John Connor looks unnervingly like transporter chief O'Brien.

5) Skynet's repeated inability to design and program an antagonist...maybe it should just send itself back in time, replace itself at Cheyenne Mountain, and instead of nuking humanity, demand a commission and a pension.

You don't have to love the last two post-James Cameron sequels but at least those conjured up some relevant ideas unlike this trash-fest which was without entertainment, merit or even a single though in it's body.

They will have a field day with it especially the Crystal Skull-ish bus chase which makes the makers of SPEED face palm at how atrocious that was. I'm sure even Michael Bay got bored watching it.
