I've finished it now and don't quite know what to think.
The bits where it veers towards the book (Anne cutting her hair for example) have moments of momentum around them.
The rest sort of ... dragged. Without giving spoilers, what was it, four major characters who took up a lot of screen time who weren't in the books? Plus the pretend backstories for various other characters, their relationships, their money etc etc.
I'm not a purist, I love adaptations, but there was a point where I just wanted them to start telling the story of Anne herself.
The morality stories also felt too rammed down your throat by the end (you know, "don't be racist, don't be homophobic"). It grew too overt and moralistic and an advert for modern accepting Canada, rather than "here's the story of a girl".
I began rolling my eyes at just Anne The Perfect and Gilbert The Woke, or Anne The Absolutely Tortured Orphan From Evil McEvilville Orphanage. 
Having said all that, it's still not terrible. The actors of Matthew and Marilla and Anne make it worth watching.
Also is it me or does Anne with a shortcut exactly like Mia Farrow in Rosemary's Baby?!
