In contrast to the silent narrative in The White Drake, this Rise to Power movie had a great deal of dialogue. It displayed an amazing amount of wit and light-hearted characterization between the Lich King and Anub'arak. My favorite line was when Arthas complains how much fun it is to "constantly ressurect an oversized roach." I don't want to discuss the ending of the movie, since it would definitely give a significant spoiler. But let's say an old, ancient foe of the Alliance returns to join the Lich King's army.
A Dead Bug's Life is a beautiful movie. The graphics are intriguing and well done, seamlessly integrating to the story. You can really see how A Dead Bug's Life won its prize.
