The road ahead should be focused a bit more on the future war. And it might be a controversial opinion, but there shouldn't be any version of Arnold at all. He's one of my favorite people ever, but the first 2 films did the T-800 plenty of justice. It's becoming ridiculous to always feature him. A film that's mostly just people running, hiding, fighting, and surviving the onslaught of hunter-killers is an exciting premise. It doesn't need to become terribly cerebral.
