For me to review this issue correctly, I would have to allow for spoiler alerts. In all good conscience, I cannot reveal ANYTHING to the fair reader because this issue was so poetic and triumphant as a single issue, you are just going to have to read it yourself.
After I read the sixth chapter of Final Crisis, I silently rose from my seat and replayed the issue in my mind like a bad memory. The kind that you witnessed first hand, but still can't believe it happened. Trying to piece everything together, as if you missed something. Not only did I reread the book five times in a row, I found myself flipping to specific scenes over and over again throughout the week. I'm not sure which scenes were better than others, because this issue is just so full of DC universe nerdgasms.
All I will say to make the review complete is... this is possibly the single, most important DC book out now. Put the Amazing Spider-Man 'Obama' book down and pick this up instead. Not only will you save about $50, you will not be disappointed.
