It's decent so far. I'm not bored and it's at least offering some heart-pumping moments.
I think my biggest complaint is that I find it hard to believe that a 6 year old is that smart. Or that these 11 year olds are that smart. Oh wait, they did just explain some unnecessary details to Don and Gilda. So I guess they're just stupid when the plot demands it. Ray's motivations seem pretty vague right now too. Pacing wise it could also be a bit better in places, I guess they aren't actually going to leave until the final episode.
