There are just way too many. Bran has like.. 3 chapters the whole book and Sansa got cut completely. Those are 2 of my fave 5 POV characters in the series, along with Jaime, Arya and Theon. Tyrion isn't a favourite of mine (Though I still like him a lot!), and spending so much time with him is irritating. I don't hate the Dany chapters nearly as much as fandom does, but I'd agree they were too numerous.
The 2 least interesting plots dominate the book. I find myself praying the next chapter is a Reek one whenever I'm on a Tyrion chapter now. The best antidote.
