Honestly I think the last one could have actually been good if they hadn't half assed it. They had a really neat idea in having things change back in the 80s it just went off the rails so badly like all the other sequels. Oddly enough each of the sequels and reboot have interesting bits and pieces to them but they never manage to be totally good. The sad thing is my favorite part about T3 was the fact that there was no way to stop it from happening, every thing they did in all the movies was simply putting it off a bit.
It reminds me of a theory that nature hates a vaccum so if you were to stop Hitler from becoming anything more than a landscape painter the universe would replace him with someone who actually may be worse.
I'm not keen on destiny or predetermination but we do know that nature seems to like things tidy and clean so messing with timelines could cause issues like this. The terminator 2 novels and comic books did it a lot too, and in cases way better than the movies, including a T2 one where everyone actively realized that something changed in their past and their memories were changing enough to be noticed in the future.
And I have more faith in this one because the creator of the franchise is actually going to be writing it. That said i hope it's better than some of his last films.
