This kinda has spoilers.
The only thing, in my opinion, that saves this book is Dors and Demerzel. They are awesome, awesome characters and a true continuation of Asimov work about robots. Ah, also, Wanda Seldon is pretty impressive too; if a bit stuck inside very narrow actions: she's too perfect and has too little grey area, in my opinion, to be a complete character.
The book is generally boring, it has too many conversations that could have been avoidable and that just are there to fill pages, or so it seems. I skipped through most of Hari's meetings with politicians and business people.
Still, the middle part about Dors is really good and if you liked Foundation, you should definitely read this.
