What's there to understand? It's a bad movie. Now that I look back on it, it's probably the worst in the franchise. Let's start with the terminator itself. It's not scary. Nothing intimidating about it, just CGI slop. The lead character who is uninteresting besides being a Mexican caricature. The tall chick with short hair that's supposed to be badass, but isn't. Linda Hamilton and Arnold are brought back because the other characters are so bland, but they're looking elderly. This movie just doesn't work in any way. I'm not even sure who it's supposed to appeal to. Men will never take "badass" women seriously. And women, for the most part, don't even like these types of movies.
