This has to be, the biggest waste of time I've ever watched. I don't care enough about this show to care about revealing any spoilers. Here's something you should keep in mind, if you even decide to watch it: This show LOVES to bounce between time periods, at random, with almost no relevance to each time period when it decides to snap back. Most of this show is a flashback, where you spend most of your time on some useless garbage, backstory with no sustenance.
One of the things that stood out was the fact that everyone could fly and had superhuman strength. So I was wondering how in the h*ll that happened. You find that out in episode 8. The actual reasoning? Because they endured the trials set by this island, they were now "chosen" to acquire this unknown power provided by this Windows 95 screensaver, ethereal, thing. So now they can fly. Oh and the suits came with them. Some Power Rangers meets the Caped Crusader type BS. Only worse.
On that topic, this show pretty blatantly rips off the Justice League, pretty much does try to change the appearances. They decided only towards the end to make the shows' flashbacks some amount of continuity. The first 5 episodes are spent quite literally pinballing around everywhere. There is no coherence between the present day clip, the flashback, then back to the present for 30 seconds, before it goes back again to the past.
Actually it would probably be better to say this story is set in the past, the flashes are set as glimpses into the future. At least that way it makes some sense. Just don't watch this compilation of a show. If you do, bring some Tylenol and or alcohol. You're gonna need it.
