firstly Rowling has shit political views. we all know this. I do feel bad reading this but I got it from the library and shes getting no profit from me. unfortunately shes a good writer.

pros:
- very gripping, couldn't put down
- characters were interesting and complex overall 
- did a convincing job of showing online spaces

cons:
- the sheer pettiness underlying lots of her comments is a lot. the whole plotline is narcissistic. I get the point shes trying to make (toxic online spaces driving innocent creators to misery. bad ppl hiding building up gullible fans with claims of creator's being homophobic/racist/ableist, etc. ppl being blinded by this that they miss true predators, sexists and racists) but it misses all the joy of online friends, and generally reads like shes bitter about the criticism.
- she also misses the very real need for criticism. she mocks "SJWs" but her own views could be called that by some alt right. she's determined to see that fans are acting as a mob with no critical thinking skills, where I think shes blinded by confirmation bias and her ego and lacks the ability to be compassionate and tolerant. anyway. her views are made very clear in the book and it feels petty.
- underwhelming ending, not helped by me thinking for some reason that this one the last one. was disappointed.
- its dragged too long now. think this should've been last one for sure.

overall, disappointing and frustrating, because it was good up until a sour end, much like her.
