So, wow. I don't get how this is getting so much hate. I really have no idea.
This is a very down to earth episode about the human mind and helicopter-parents pushed to a Black Mirror standard. I can get behind everything unfolding in this episode and at all times am mesmerised at how interesting it all is.
I loved it from beginning to end. Fun to analyse, but I'll do that for myself at some point when rewatching. I'm sure there'll be a lot of videos online doing just that. I hope this doesn't become more hated on than it already is. I mean wow, it's a touchy subject for sure but ... give it a chance. Some of the flaws in here some see I just don't. Heads off to all the people involved and to Jodie Foster.
One of my favourite episodes of this whole series.
Also, the age thing with Sara - I do not think it is an issue. But that'll be a spoiler if I elaboreted on it further. I think there are theorys that could clear that up or she just looks four years older. That is life, that happens, nothing bad or flawed about that.
