While quite a bit better than the abysmal Braniac Attacks, this foray with Brainaic is probably also more forgettable. Of Superman's animated movies in the modern DC line, this one also came off as a very head-scratching choice for an adaptation. At least Superman vs. The Elite was based on a very well regarded story as was All Star Superman and even Superman Doomsday. Superman: Brainiac was an okay story, but not an obvious choice for a movie.
I may be alone, but one of my favorite elements of the movie is the design and depiction of Supergirl. For my money, this was the best she has ever looked on screen.
Supes on the other hand has looked better.
