went too fast. Dany turning crazy. Jaime going back to Cersei. Arya quitting her revenge plot. These are all good story lines if given more time to develop.
But when jaime’s return to Cersei loyalty is the product of a single conversation with Brienne, it’s lame. Give that story line a six episode arc, and it’s great. Same with all the others.
Just a bad idea to try to cram this much story into such a short cycle.
