This isn't your father's Justice League! Justice League: Gods and Monsters may have a roster of DC's Trinity, namely Superman, Batman, and Wonder Woman, but that's where the similarities end.
In this incarnation Superman is the son of General Zod and not Jor-El, Batman is a much more powerful version of Man-Bat, and Wonder Woman is actually a warrior princess from New Genesis and not Themiscyra.
My only regret with this movie is that it's relatively short, with a runtime of 76 minutes. Otherwise it was great seeing old characters reimagined, and used in new and intriguing ways.
This Justice League by the way doesn't pull their punches. In fact, you might say they go out of their way to be quite brutal to their enemies. However, their motivation is still in the right place, and they are in fact heroes.
QBF Rating: 3.5/5
