Arnie was not one of the two main characters but still served a purpose and added to some unexpected humor for his role. The two lead ladies were excellent, not being caricatures or unrealistic superheroes. I thoughtI felt the touch of James Cameron that had been missing for so long, and Linda Hamilton was still able to inject the Sarah Connor character into a place where the numerous franchise revisions of the future had sort of removed her relevance. For a franchise with this many sequels and re-imaginings I was quite impressed. I would be happy if they left this as the end to the series though.
