What did you expect? The show is about a group of cadets, so of course they're going to be young.
And Mike Dopud
who plays General Black hardly looks 12.
I enjoyed it. They've clearly put a lot of effort into the production to create the feeling and tone of the games as well as the previous live action shorts. Though in that regard they have a lot to live up to, because even for commercials, those live action shorts were extremely well done.
It was nice to see they got a actors who can actually act and have a screen presence beyond whatever dialog they're spouting.
I recognized several locations from other shows, namely BSG and Stargate and I wouldn't be surprised if those same woods served as the backdrop for numerous alien planets throughout stargate.
I'll definitely be tuning in for the next episode.
