This season so far has put significant emphasis on relationships and characters' psychological problems (what I meant by "soap opera" in the title). This episode had less of that, and more actual action that advanced matters not related to people's personal problems.
If, like me, you watch shows like /Young Justice/ to see metahumans being, well, meta-human, then you probably don't want to see characters staging interventions for other characters, or crashing their lives because they're having trouble accepting the death of people they care about, or resolving family problems. We all have real life for those things, or countless other shows that are not about metahumans. This season has been very disappointing for those who want to see metahumans using their abilities to go beyond ordinary human concerns. This episode was better, but still far worse than just about any episode of the earlier seasons (which were by no means devoid of relationship stuff!).
On top of the above, it seemed almost surreal to see some characters trying to talk to others about getting their lives together while, quite visibly, the whole world was in peril.
