It's a nice tribute to him. The saddest part was listening to his children talk about him and realizing how young they were when he passed and that his oldest son had to become a father to his younger brother.
The only thing I wish is that they could have delved more into his film career. Reeve should have been a much more commercially successful actor. He had the skill. It could be argued that he couldn't escape the Superman character but it seems he was much more interested in smaller, 'artistic' film roles over the more mainstream ones.
