The first half of this was uneven and it took a while to get going, but overall I liked it. There are members of the team that didn't work or didn't leave a strong impression -- I didn't like "Captain Normal" or Carlos, and the bug guy and the precognitive guy were a bit bland. Naoko Mori's character was also underdeveloped, but hey, it's Naoko Mori, so I'd be cool with her sticking around. But I liked Walter and Watts, and Marsters's character (whose name eludes me) worked out well too. I liked it that Walter is really smart and well-educated but that it was presented so unassumingly and not made into a big deal. And I liked the twist ending, the explanation of what was really going on with the mission.
I also like it that Walter told his best friend and (eventually) his mom about his abilities and new job. I'm not fond of the convention of heroes keeping their special abilities/affiliations/technology/whatever secret from their friends and family. Not only has the whole secrecy trope been played out, but it limits the friend/family characters' participation in the stories. I always think those characters become more valuable to a series when they're let in on the secret. So if this had gone to series, I would've been glad that they weren't going the "I must keep my secret from my loved ones at all costs" route.
A bit weird hearing Naoko Mori and Stephanie Jacobsen with American accents, though I gather Jacobsen used one in Galactica: Razor. Kind of a coincidence how both the female leads here ended up being played by Asian or part-Asian actresses concealing their British-Commonwealth accents.
It's also ironic that Brandon Jay McLaren, who played the one regular cast member (other than Andrea Martin) who isn't a member of the superhero team, is himself a former Power Ranger. He was the team leader on Power Rangers SPD. And he seems to be having bad luck with pilots this year, since he was also in Ron Moore's 17th Precinct.
