Like KC said, it's usually decent right after the episode airs. Some people may point out something that they didn't care for, but it's normally pretty good. Someone's critique won't change my mind after the fact regardless.
I gloss over some of the predictions, but haven't put stock in any of them. There was a fairly in-depth spoiler that was put in there last week that was completely off. I'm pretty convinced that outside of the cast and crew, nobody really knows how it's going to end and any "inside info" is a bunch of crap anyway.
After the show surpassed the books, we're all in the same boat. That has kept some of the smugness out of there.
