A series of beautifully animated, overly bloody, poorly written and totally inconsequential stories that culminate in a disjointed ending that ultimately serves no purpose.
I'm genuinely not sure there's been a properly good DC Animated movie since the Flashpoint series, although the standard of the new voice acting is excellent and overall the animation quality is higher than it used to be, but the last few have been so incredibly lacklustre that it really makes no sense why they're putting money into these stories instead of further Elseworld adaptions or any of the million excellent Batman/Superman standalone graphic novels.
If you've got 90 minutes to burn, this one is fine, but it really doesn't add anything if you've got fond memories of the adaptions of 10 years ago.
