Weakest POV in that book is probably Cersei as it's slightly too over the top. Still highly entertaining though.
Cersei's chapters are some of the series' best black comedy. Watching her fuck everything up whilst crowing about how clever she is is glorious.
Cersei's chapters are the highlight of AFFC and among the best parts of the whole saga so far.
Removing everyone with an ounce of brain from the council, putting some random bastard (or not random,I forget his background) in charge of the fleet, allowing Faith Militant, telling Braavosi bankers to go fuck themselves, hatching the most bizarre and convoluted plan to get rid of all her enemies - what could possibly go wrong? Well, everything. It was indeed glorious.
