I can't stand the most cloying of wrap-ups for a story like this. It is the most unsatisfying ending that there could have been for me.
The moment that they were showing the DR2 character video threatening the world with despair, I was like "Oh neat, maybe they actually did do something cool and unexpected after all." Nope. Then Makoto was crying about Kirigiri and I was like, "Well... I guess they kept her dead, even though it was a stupid death. Well, unless in the next moments..." And, yep.
The return of the DR2 cast was all sorts of crappy. No design update for the most part, which doesn't make sense, and what they actually did in this episode was the most frivolous nonsense there could be. Goes counter to DR2's ending; devalues it. Would have been okay with Nagito, but the rest of the "dead"?
I remember telling someone in this thread earlier about how I feared that what they had in store for the DR2 cast would be saccharine and overly optimistic. That person was arguing that, even were they to be restored, they would have to deal with their actions and having messed up bodies and blah blah. Yeah, sure, that ending really showed that they're bummed out about life and are not looking forward to their future in the most hopeful way imaginable.
