The plot was pretty confusing. It was definitely interesting, don't get me wrong, but it was solid until the last episode happened. That was so cringe! A 9 year old going berserk and doing a darn good cleaning job afterwards. It's a little too... Weird.
That episode would've been believable if there was some psychological explanation of the kid and how maybe a traumatic journey led her to do so.
It's too weird for me. But the rest of the episodes were really good.
