I've of mixed emotions on this book. It's got potential, but it's not all the way there. 
 On the downside, at least two of the protagonists (Superman and Wonder Woman) are quite unlikable, and the book overall is full of too much pointless fighting. And, if you were hoping for another bwah-hah League, this ain't it. There are moments of funny, but they're far and few between. 
 On the upside, Giffen envisions an intriguing future. The ethical and existential questions concerning the main characters are especially interesting. In addition, the villains that he's created in the Five are original and esoteric. 
 Overall, this book earns a solid 3.5, but I've jumped it to 4 stars because it seems to be trending up, not down. 
 I'd prefer to have a Legion book back, but in the absence of other 31st century stories, this ain't bad.
