It does. Basically it might as well be a prelude story to Crisis on Infinite Earths. With it connecting our heroes even more than ever with Barry and Oliver understanding their pain and triumphs after this event. Plus there is a surprise with Superman that is pretty great for someone who is enjoying his more modern adventures.
