This new one is so bad, it's mind numbing. It's basically fan fiction with "wouldn't it be cool if (fill in the blank)" ideas shelled around a cash grab to remind us that Arnold Schwarzenegger can still wear a leather jacket.
I'm not big on T2. It was cool when I was a kid, but the first film IMO is the only great one. I prefer that dark 80's vibe, and the machine was something to fear. In T2 they made him a sidekick to an annoying kid. Every Terminator movie after that tries way too hard to replicate T2.
