I do kinda like the anthology nature of it with the different storylines that still manage to cross over each other thanks to the persistent use of the time/date stamp. I did appreciate that it took them weeks to find the crown of Arion given the size of the area they had to search.
The Legion revealing themselves to Superman was interesting as it indicates that the 'event' they need Superboy to be at is on the occasion of the 20th anniversary of the formation of the squad (given the call-back to it being the 10th anniversary in the end-credit tag). Still not sure where the overall arc is going, but I definitely want to smack the shit out of Beast Boy despite it being an accurate representation of depression.
