The preview chapters have been fantastic though? The show isn't exactly a staple of fantastic writing anymore.
The Aeron preview chapter, linked earlier in this thread, was a fantastic showing of Euron - definitely better than anything in the show (of Euron) so far.
Edit - Also what's with these very reductive replies? The original poster made a point and you both reply in a condescending manner. It's quite pointless, doesn't promote discussion or anything. I'd genuinely like to know why you'd be negative on the preview chapters? I read AFFC and ADWD quite late and still found both enjoyable, though I understand people's complaints of them being heavily padded. The preview chapters have been a massive improvement on this front, given we can't fully judge until we read them in the context of the book.
With regards to Jon's Resurrection. I hope we see something familiar to either show Benjen or Cold Hands. A decaying body, but his mind remains fully intact as a result of warging into Ghost. The cost of victory against the others being the spell keeping him alive would be a bittersweet ending. I don't believe there will be an iron throne come the end of the books, and I hope the same of the series too.
