I think the show was alright, though I did binge it which tends to make anything more watchable. The focus on the code is interesting, and very understandable from Sheldon's part. When your the top dog, you have no one to answer to but yourself, so the code is created as something to answer to. Its the ultimate check, the line in the sand that can never be crossed or the goodness starts to die.
Its well done in that people start dying, and people very reasonably say "if the code causes good people to die, screw the code". But Sheldon has to look beyond the hear and now. He knows that power corrupts, and that ultimately without the code you will have something far worse than a few dead superheroes....you'll have a league of superheroes that have all become villains and don't even recognize it. But that's very very very hard to argue when their are dead kids on the deck.
Ultimately the backstory was my favorite part, I considered that the real A plot, and the modern timeline was B. I was disappointed at the end of that though, the way they kept eluding to "the price we had to pay to get these powers" I was half expecting they had to sacrifice family members, or that Sheldon has actually been making constant sacrifices to some ancient being over the decades or something. The "price" was going someplace, crossing some bad terrain, and "fake forgiving" your fellows (seriously that was the worst part, they were like "you have to make amends"....Sheldon and Walt have a little shoulder pat with each other and all is well with the alien space machine.....wth?)
I mean sure it was hell of an adventure and very dangerous, but it didn't match the ominous way they kept referring to the "price" and the "sacrifices".
Let me finish that the teleporting rod is awesome, probably the best scene in the show was when Starfox's kid has been threatened by the "Big Boss", more specifically his friends. The man has tried to make amends, tried to do things the peaceful way. But when finally cornered he bares his fangs, sends the rod into the Big Man's heart and back again like it was out getting pizza. Its shocking and awesome, and really speaks to the guy's character (not quick to kill, but willing to).
