In both parts, the episode carries a very eerie tone that's emotionally haunting through its atmosphere, music, and especially the voice acting as its centered mainly around the character of Matt Hagen, who's a realistic and relatable character regarding his obsession with the Renuyu. He struggles with his addiction the same way how an alcoholic or a junkie would. He's never happy, knows it’s not good for him, but can't quit it because it helps him deal with his pain and give him the strength to move forward even though it's slowly destroying him and making him do extreme things by order for him to get more of the Renuyu as he refuses to listen to the pleas of the people close to him, which is quite ballsy for a kids show to tackle on. And it isn't hinted, downplayed, or played out like a drug PSA; the writers take it very seriously to the point where it's chilling to watch Matt's torment.
What heightens the levels of drama in both parts of the episode when we're not with Clayface, is Batman's determination to search for the person who's been impersonating his alter-ego. There's no mystery to it, but to be fair, it's not really being played-up as one. We know that Batman will eventually come out of this struggle fine in the end; however, we're still left with the question of how he will accomplish it. After all, Bruce Wayne is in danger of being imprisoned for his crimes, and if he's locked away he won't be able to protect Gotham, thus causing his vendetta of discovering the identity of the person posing as him to be more engaging. Batman has had plenty of moments of striking fear into the hearts of criminals, but here he comes off as more of a threat because you're not completely sure if he's actually going to kill the thugs that he's threatening if they don't talk, which is quite intense for the near-death situations that Batman puts them in where you feel the weight of their lives being at stake as you listen to Batman's cold and demanding voice delivered effectively by Conroy. Conroy also does just as creepy of a job for when he acts sinister for the scenes when Clayface is impersonating as him.
I shall review the rest of the episodes from the first season soon.
