We all know the Justice League and its main member, Superman, and how he is the son of general Zod, was sent to earth, narrowly missing capture by Lex Luther, and raised by migrant farm workers. Okay, maybe you don't know this version, which has a much darker, bloodier group of superheroes, and now someone's trying to frame them for the murders of scientists (shockingly, murders they did not commit, this time). This was an enjoyable, animated film, but I think you'll enjoy it the most when you have a least some general idea how the DC universe is being turned upside down, otherwise it is just a bunch of meaningless names with much less impact. Definitely worth it if you're a DC comics fan, but otherwise probably not. See if you catch the references to drug use and sex.
