I really do think if they limited the Synth/Golem to just the 1 prototype, Wendy. it would have flowed better, having 5 kids is a bit much, and honestly, with the abhorent thing of killing the kids to do it, that having just 1 volunteer would be a better PR decision. Story maybe have had to have a 2nd one, so just name that one Peter, and you have the Wendy and the mashup of Slightly, Nibs etc. and have Wendy succeed by focusing on her brother, where Peter goes into dysfunction.. ( For some reason I see the Robocop 2 scenes where they try to make a #2 and it goes horribly wrong) with morrow messing with him.
Anyways just a thought.
