I thought last nights episode was great. My only complaint with this season and last to a lesser degree is that things have felt rushed but they've had 7 less episodes to work with, so not a shock.
This has always been where Dany's story has been going, ppl just haven't been paying attention. I don't think this betrays Jamie's development at all. Its not like he killed a bunch of babies gettin back to Cersei. He made a decision to be with the woman he's always loved. What would have felt disingenuous to his character would be if he heard Cersei was going to die and decided to just say **** it and live happilly ever after with Brienne.
I don't have any problems with the story telling choices being made. I'd be willing to bet that a lot of the major developments are in line with what GRRM has planned so not sure why D&D seem to be getting all the backlash.
I think the acting, directing etc has all been top notch. Ppl just had certain ideas about where they thought this was going and are in their feelings bc it's not playing out that way. Most ppl I've talked to in person have enjoyed the new season. Seems the ppl who continue to watch a show they don't like are the much more vocal crowd online.
