I was very surprised at how effectively Jessica was utilized in this film. When I first heard that she was going to be used, I suspected that she would just be rotated in with no fanfare like John Stewart in Justice League Dark. Instead, the narrative not only engaged her as a unique character, but it adapted her backstory closely from the source material. She really shined, no pun intended.
I was marginally disappointed with the regression to the JLU character designs. They were thankfully updated, but we were still subjected to artistic choices like Batman's brick chin and giant fox ears, not to mention that Jessica's hair looked like drapes. However, some of the power effects like the energy blasts from Validus and the antimatter touch from Mano were extremely well done. I hope the DC animated movies don't keep using modified Timmverse designs, but if the stories are as good as this one, I can certainly overlook them.
