Very true to it's title name.

Damian stole the show, and it's no wonder the title is actually referring to him than just being a batman animated movie.

Despite being cocky, he's also incredibly skilled, determined and quite focused on his goals, resolving to complete it at all cost. You can admire his "discipline" (in some ways he is) and dedication.

Also, you pretty much empathize with him as well. Throughout the movie, I can really understand why he feels the way he does and I was actually rooting for him to win the entire time.
