I have just seen the first 5 minutes this morning. Can't say much about that.
You really didn't like the Battle of the Bastards in the last season? Nor Aryas killing of the Freys? Nor Samwell Tarly curing Jorah Mormont from greyscales? I thought it all great stuff.
Arya was good but the battle was predictable along with the killing of Wun Wun in Winterfell. Jorah has proved to be a popular character and curing him was again, predictable.
The books and series (at the start) were good as there was a real element of unpredictability in them. You didn't really now what was going to happen next. As soon as HBO had more of a say in what the story line was going to be it became less enjoyable for me.
Don't get me wrong, I'll still watch it and probably like it I'll just be disappointed that it will follow the standard fantasy tropes.
