I was a huge fan of the original storyline when it was printed in comics and was wondering how they were going to fit all the storylines into a 1.5 hour movie. They did a decent job of streamlining everything by changing around some key elements. Part of me wishes they had stuck to the original story, but part of me is glad they did something different to keep it fresh. The story is still fairly engaging and there were a couple twists I wasn't expecting. The voice acting is pretty good (besides John Henry's voice should have had a bit more bass to it imo since in the comics they described him as having more of a James Earl Jones type of voice) and the animation is above average, with spots of low effort in certain scenes.
Overall, I'd recommend it to anyone who's a fan of the DC universe.
