Ridiculous. Instead of waiting until he can gain backup from the Justice League, Superman rushes into danger with a band of neophyte heroes to liberate War World from Mongul. Makes no sense at all.

@ZoomingColorfulSailor: you didn't read the volume before where they explained that the league can't leave Earth as they're meant to protect it that's why he took another team with him and some of them disagree with Superman's strategy, you should read before commenting
