I watched all of it. I actually liked it a lot.
It's not incredible, but it's a simple and fun cartoon and there wasn't any agenda-pushing or political nods that I can see, other than the main villain in the end being a very patriotic US government "Man in Black" bent on conquering the galaxy. Though honestly at this point portraying the US government as corrupt or evil is like calling a horse a horse, not to mention it's meant to flip the classic humans vs. aliens comic book plot fodder on its head
The aesthetics were cool, I liked the setting, each character got some time to shine, things didn't always turn out as expected and everything got wrapped up with a neat little bow at the end. The message of the show mostly revolved around the classic "it ain't the powers make the hero" and dealing with feelings of inadequacy. It seemed almost like they didn't expect a second season at first, since everything got resolved nicely and they just casually name dropped a potential future threat just in case they did. It could have easily stood alone as a 10 episode adventure until the very last couple minutes.
I recommend it. It was a breath of fresh air in this desolate, political wasteland we call western animation. Don't know how season 2 will turn out but I'm optimistic.
