Everything got wrapped up in a neat bow in Issue #4.
Overall, I thought the concept was of the mini was neat especially after the massive crossovers with Final Crisis, Blackest Night, and even the New Krypton arc in Superman's own books; which I guess this was the final chapter. But I thought maybe they could've thrown a couple of tie-ins to the main series to flesh out some of the side plots. A lot of cool stuff was rushed through or done off panel and I think that diminished the story, or at least my enjoyment of it.
Anyway, while I loved the relatively cheap price of the books, the last two issues were a little too slight. I wish that at least they had been beefed up so we could see more action, like the rescue of Natasha Irons, more battles against the Kryptonians, etc. Issue #4 moved at too much of breakneck pace. I wish more pages could've been devoted to Supergirl v. Ursa and Non taking on the Justice League. Or Supergirl v. Superwoman, or more fights with Assassin and Guardian and Atlas and Steel. Also, Natasha getting some payback. That all would've been sweet.
It might be cruel of me, but I was hoping that Krypto would be the heroic sacrifice. I think his death would've had been more meaningful and poignant than the exile of Chris Kent. The solution to save him was just too handy.
I'm a little disappointed that General Lane killed himself. So Kara really couldn't have stopped that bullet? It would've been nice for Lane to have to pay for his crimes. And it would've left him around for future storylines.
Despite its flaws, I still enjoyed War of the Supermen. I thought it was better done than the main four Siege books, in comparison, with a more satisfying conclusion.
Question, what happened to Mon-El? Did he get sent back to the Phantom Zone in a separate book? I was wondering about his absence in Issue #4 and then I saw the scene with him and Chris Kent.
