I absolutely love this show. Whoever is running it understands both comic book geekery (which I love) and young adult fiction (which I love.) I don't think I could love it more. OK, there is one thing which I will talk about later when I get into the spoiler section. And it does get a little stereotypical in it's portayal of non-white people.
But first, the non-spoilery stuff... assuming you've seen season 1.
Brilliant incorporation of season 1 elements while keeping it fresh. The time jump was perfectly executed. I love the new characters. I do wish there had been more time for the kinds of character development & team-building we had in the first season. But I absolutely loved the distinct "families" that emerged. (Sidebar: Always bet on the Bat Squad.) I could have done without the Mal/Karen storyline in favor of more of our core group.
And I'm just going to go ahead & say it: I have a crush on Nightwing.
Now. Spoilers....
No, for real. Spoiler alert. You've been warned. Why Wally? Why why why? In my head, that last bit just didn't happen, & I still have my Kid Flash. All the mourning for Artemis, when we knew she was safe, seems over the top when we get almost no eulogy for Wally. I know there was supposed to be a season 3, so I'm guessing/hoping there would have been some effects shown. Also, the possibility of some sort of resurrection is how I justify my complete denial. And while we're on the subject of spoilers, dark Aqualad is so so awesome, as is Nightwing's angst (hidden under his humor) and Wally's doubt. The increase in maturity for all of them shows, as does the weight of the original 3 each now being on their own journey. But Aqualad as a villain is amazing, especially with enough of a gap that we have to accept that it could happen to anyone... and Aqualad was one of the best.
If there had been a season 3, I would have been all over it.
