Watching animation doesn't have to be all about storyline, time line or which "universe" this exists in. This was a fun story and they told it well enough to keep me entertained. In the end this may be just a one off type movie. No sequel, no prequel and a lot of mini stories wrapped into 1 movie. That is fine with me. It was enjoyable to see all the different mini-verse story lines..where it could go, where it came from. I sat back and just had fun with it. If you go into this expecting some revealing craziness that you don't know about Superman you will be disappointed. If you just go into it looking for a good movie to watch with your kids and maybe remember when you were a kid, this is a good one.
