So far, a well done adaptation of the Crisis comic book series and CW series. Love all of the cameos.
BTW..... many people seem to be upset that The Flash dies in COIE. Just remember: we've been led to believe (because of his show) that it's Grant's character who is doomed. My money says "The Flash" that dies will be JWS's 90s TV-series' "Flash" who will die.
Tom has always said, "No tights. No flights." Playing into the Superman II angle where he gave up his powers to marry Lois and have a normal life was an excellent touch, IMHO.
It would be great IF this (and other crossovers) COIE would be marketed and released as a single DVD/Blu-Ray.
