Arnold being himself was what made him a star. This kid is likeable enough but he has not (yet?) got the charisma of the Oak. He has some resemblance to Arnold but if they would wait a couple of years, Joseph Baena might grow into his father's physique and then it's all over for the rest of the wannabees. Remember, the apple doesn't fall far from the tree but cannot help but grow up in it's shade.
