It's inevitable this will be compared to Red Son which so far by consensus is better than Mastermen but there is still some good stuff explored in this issue. Unfortunately being a one-shot, the story abruptly concludes while we wish for further developments and honestly the briefness of this story is its ultimate downfall. Overman is hinted at being troubled by his past and is spending considerable energy trying to escape his past while still maintaining his power over the New Reichsman which is pretty much a Nazi Justice League. An Uncle Sam hero and his freedom fighters show up for only a few panels before bombing the hell out of a few places which makes you wonder if Americans are now the primary members of terrorist movements. Overall, there's a bunch of interesting what-if's that never gets fleshed out which is disappointing. But I'm afraid even if it does get fleshed out, it'll just bear a lot of similarities to Red Son so Morrison really needed to get creative in order to separate his story from Mark Millar's which didn't happen. Also, while not everyone loves Jim Lee's art, to me it's always a treat to see interior work from his pencils. I wish they made this issue longer, I would've gladly paid $7.99 for a jumbo issue like the Multiversity Guidebook if it meant for space for story-telling.
