I don't even like most of these characters, and I'm still mad that once again- like during Flashpoint- the writers have basically rebooted the characters that people have been watching for over a season and a half and seem to expect that audiences will love them just the same. Yes, two of them got memories back this episode (and presumably, others will too; hopefully at least William) but dangit, just because they look the same, talk the same, doesn't make them the same characters. It's a real f-you to viewers, IMO.
Also, I'm still confused about the post-Crisis universe. We've seen other planets, yet I still keep seeing characters remarking that there is no multiverse anymore. Are all those other Earths just identical planets in identical Milky Way galaxies elsewhere in the same universe now?
