I wouldn’t exactly call Arnold a self-aggrandizing vanity project for Arnold Schwarzenegger, but it stays overly positive while only briefly glancing over controversies from the star’s past. My biggest problem, though, is that I didn’t really learn anything new. Obviously, that will vary from person to person, but this documentary plays out like Arnold reading his own Wikipedia page for three hours. It’s not terrible, as Arnold is immensely watchable even as he does nothing more than sit in a chair and smoke a cigar, but this series would have benefited from additional commentaries from his contemporaries and a less sanitized examination of the icon.
