The main-page description of the stories in this book is pretty accurate. However, if you are like me, you would prefer that a title actually reflect the book, than you should know: THE JUSTICE LEAGUE, PER SE, IS NOT ACTUALLY IN THIS BOOK!
But that's OK, you still get some great stories for your buck. Superman in the jungle, weakened by an alien illness or poison, crosses paths with Predator. Sarah Connor and John Connor arrive in Metropolis, with the usual cadre of time-travelling Terminators in their wake, while the Resistance accidentally draws Supes into the future. The original retired Starman is kidnapped by magic-wielding neo-Nazis, and Batman, Hellboy, and the current Starman team up to rescue him. All have good art and good stories (although the Terminator story tries too hard on too little "legs").
And then there is the one story I actively disliked. Ghost (a Dark Horse rebel super-agent version of Kitty Pride) meets the Cassandra Cain Batgirl and Barbara Gordon Oracle team to take on... someone I don't know, at the same time he crosses Two-Face. This story also tries to be too much, and none of it actually firmed up into a believable, likeable story. There's too much sexuality in the first half of the storyline. Ghost is another one-in-a-million porn-star body and supermodel hairstyle stuffed into a costume by Frederick's of Hollywood that cannot support her figure, let alone the weapons and ammo she uses per issue. And she has superpowers on top of it. At least Batgirl looks almost like a teenager. In a ninja outfit, but still a teenager. Sorry, ladies, I know this is the only tale here where the women kick 100% ass, but they are 100% someone's fantasy, and not good story material. If this tale had a good story.
Ah, well. Free from the library, and lots of cartoon action. Who am I to complain?
