Pretty decent stuff. The novelty of a younger naive Supe's is good and I liked the pacing of him getting to know his abilities. Lex is pretty much as per but Lois isn't quite the spitfire unwilling to do much she's not in charge of as in later years and that was good to see too.
The Martian Manhunter is always good with his disguises and laid back, oh ,yeah I'm alive still so why don't you handle that! Lobo is fun and I particularly liked the voicing work of Ryan Hurst here, who kept him dimensional enough.
I appreciated the way it's drawn as it fits the older younger style and not just Emperor's new clothes.
They seem to be on a roll, last two films have been really good.
