Jaime's one chapter was definitely filler and out of place in ADWD, but in all honesty, I would've been more pissed if GRRM still left us on a cliffhanger on whether Brienne is actually dead or not. I think his chapter was fan service in that regard.
I'm sure if GRRM could re-compile his novels, he'd place Arya, Jaime, and Cersei's chapters in AFFC. They don't have much place in ADWD. I also agree that Quentyn's early chapters should've been cut and his arc would still be served if his 1st PoV was the one directly after Barristan first confronts him and advises him to go home. I thought Quentyn's last chapter though was one of the best in ADWD (loved the portrayal of the dragons as mere beasts, rather than mythical, magical beings that we see in every other fantasy series).
Speaking of Quentyn's arc...I'm looking forward to seeing if/how Ser Gerris and Ser Arch's roles expand in the series. GRRM has a way of introducing seemingly minor characters in one novel, only to push them to prominence in later books (ie. Theon from GoT to CoK, Ramsay from CoK to ADWD, Val from ASOS to ADWD, etc.). I thought Drink was a vain punk early on, but I was surprised by his absolute loyalty to Quentyn (I was suspecting he'd betray him or desert him, don't know why), and loved how he shat on Dany at the end. He seemed to be the first character to really piss on Dany's character and I loved it (but that's probably cause I hate Dany)
