THE MIXED BAG STUFF
-The show has a very mixed tone in regards to how it approaches the grittier side of things. On one hand, the show, on the surface, is pretty upbeat - brightly-clothed people fighting other brightly-clothed people, doing brightly-coloured things. However, there's moments of what you might call..."extreme grit," I guess. As in, people die. Not just protagonists and antagonists (though that happens), innocent bystanders as well, and, well, not always in the best way to go. I'm honestly not sure whether I should call this a pro or a con, because on one hand, these moments can be very powerful. Sometimes for the main characters (e.g. guilt over killing/over innocents being caught in the crossfire), sometimes for the secondary ones. For instance, a parent's child is killed accidently early on (said parent is actually one of the villains), and to see how both parents react to learning that their son is dead...honestly, it's powerful stuff. Not for the standards of the genre, I mean powerful, in general. So basically, you have these excellent moments of character writing, yet at the same time, there's tonal whiplash involved as well. It's whiplash that doesn't bother me personally, but I could see it bothering others.
-The clash in tone also extends to the antagonists. We have the "Injustice Society of America," but their overall goal is to actually help the country. Just, y'know, through mind control, and 25 million dead. Little things like that. I'm actually not complaining, I'm a general believer in the mantra "bad guys don't see themselves as bad guys," and while there's exceptions that I still enjoy, I think moral ambiguity does work here. However, the reason I'm listing this under "iffy" is that the tonal whiplash extends to the ISA as well. Some of the characters are given good material to work with (Icicle, Brainwave), since their actors can go around in their civilian forms, still convey menace, have emotional lows, etc. Others, like Sportsmaster and Huntress, are just goofballs. It's testmant to the show that Evil Casey Jones can still come off as a threat, but he's still Evil Casey Jones, and fighting with a baseball bat and using puck grenades at the end of the day. So on one hand, you have some really solid villains that have understandable, if basic motives, and solid acting performances throughout. On the other, you have goofball villains, and villains in-between. Like the above point, I wasn't really put off by this, but I could see someone being so.
-The worldbuilding is weird. The show explicitly takes place in 2020, whereas the deaths of the original Justice Society of America occurred ten years ago. So, in this universe, 2010 marked the end of the Golden Age of Heroes (the show's words, not mine). This is weird, because the iconography for said heroes is Golden Age or Silver Age, yet this is transplated to the 21st century. That's more of a quibble than anything else, but what really got to me is how...normal, this world is. If superheroes were flying around just ten years ago, then why is there nothing here to reflect that? It's not as if people don't know who these heroes were, but, well, where are the kids chatting about their heroes? Where's the history course on them? Where are the statues? I get that this is a quibble, but if your show has the conceit of a "Golden Age of Heroes," then shouldn't there be something to reflect that?
