Does Rex have any positive characteristics?

Rex's positive attributes in no way outweigh the bad. He's extremely intelligent, and more than capable of taking care of his family, but refuses or is unable to focus his talent enough to do so. Rex is also a dreamer, who lives in a world of fantasy..... for him, trouble means adventure, and he takes his children along for the ride.... uprooting them and raising them in a state of chaos. In the end, nothing about Rex can make up for his drinking and gambling. As a father, he is reckless, his children endangered.
