Crisis On Infinite Earths is far better than Infinite Crisis, although at the time (in the eighties) I hated it because it ruined my favourite non-Transformers comic, Infinity Inc. (Infinity Inc was set on Earth 2, where the first generation of super heroes had grown up, so the team included Batman and Catwoman's daughter, Superman's cousin, Wonder Woman's daughter and many others, all of which had to be retconned when DC streamlined their universe.) Furman was obviously a Crisis reader - much of what he did with Primus and Unicron in TFUK #150 and TFUS #75 was clearly descended from COIE.
Final Crisis just finished last week. It was... interesting.![]()
