comics. Three stages of Batman continuity are referenced:
a cinema serial;
a Superman-Batman team-up comic;
Viewing: Smallville dvds. I do not like the whole Doomsday theme. Doomsday was introduced in post-Crisis comics continuity merely to kill Superman. He does not need to be transferred to another continuity, especially not the way they do it here. Enough of a story could be generated just from Clark's adventures in Metropolis and his interactions with other characters.
