Starts off pretty good. Great to see a UK show without the usual BBC box ticking and overly PC'd.
However I felt it didn't quite go far enough in weirdness.
It's almost split into 2 three episode sections.
I'd suggest just watch the first 3 and call it quits.
The fourth episode is ok but from there it gets annoying, the new lead actress does some really dumb things a mother just wouldn't do and from there it leads up to a really stupid ending.
A decent ending might have seen it get a 7.5 or even 8 from me.
