Space Cabbie, Plas and Constantine were all amazing. All the episodes with them are pretty entertaining. It had a BRILLIANT Riddler vs. Joker episode, a very good Booster Gold one, and eeeeh that Amazo/Bizarro one was pretty cool too. The one where Space Cabbie gives Darkseid a ride, the one with Deadshot aaand can't remember much else from this show but it was never outright bad. More than anything I'm glad it happened. It was better than it had any right to be. The writers really knew/liked the comics and it shows. Not quite to the degree of BatB but eh it was fine.
I just wish J'Onn had had more screentime, or his own episode but at this point I'm used to the poor guy getting the short end of the stick.
