I went into this series with absolutely no prior information, and I'm glad I did. I knew there was something a bit odd with the orphanage (especially their numbered tattoos) but I never expected that twist at the end (was actually thinking the children were enhanced kids made for war or something, so the reveal really threw me for a loop and creepiness factor). Totally made me catch my breath in surprise.
Definitely looking forward to the rest of the series but I have a sense many death flags are waving among the children.
