I have pretty much hated this season from ep 3 onwards, although if I'm being honest a lot of the issues with the writing aren't new, maybe just hoped things would pick up with the end in sight.
I mean the whole plot of the trip beyond the wall last season is fucking ludicrous if you think about it.
Most of the other book readers I know feel much the same way.
It's a shame because there is sod all chance of GRRM ever finishing the books, so this is what we are going to get. I think the ending wouldn't have been much different in the books but I like to think that the way they got there would have been a hell of a lot more coherent.
It isn't just bad writing this season, it just feels lazy, like they are phoning it in to get it out of the way.
It's not even stuff like the teleportation that annoys me (I think you pretty much need that without making the story a hell of a lot longer) , just idiotic decisions being made by supposedly intelligent characters just to get the plot to where it needs to be, nonsense like half the dothraki turning up in ep 5, everyone being certain to die in ep3 and somehow surviving at the last moment, the whole scorpion bullshit, lethal one week, pointless the next, I could go on but I would end up boring myself!
