That's very harsh. Being a book fan myself I'm enjoying this season. I still think it's been a quality show. Each to their own I guess.
The show runners are in a impossible situation. Following the best book of the series(Series 4 being the best of the tv series too). Then adapting in my opinion the worst of the series Feast for Crows, I can imagine that book being very tough to adapt. Then with no Winds of Winter due anytime soon. Imagine having to plan after series 5 with no material after it. Dave and Dan are stuck between a rock and a hard place, lose lose situation.
Agreed on Dorne, the Sand snakes scene was poor with those dodgy accents. Then the Jaime/Bron fighting looked like it was fighting in the grass of Northern Ireland not some hot desert country. I think the scene in episode 2 in the Water Gardens looked ok but was way too quick. Saying that even by the brief clip but I think Alexander Siddig will be good as Doran. If I had to choose 1 character the show had to get right in Dorne it'd be Doran.
I thought last season was the weakest before this 1, which i think is fairly mediocre at this point.
The problem is that the amount of development that happens with john or danaery's or whoever is fairly limited at this point
and they haven't bothered introducing any characters for 2 seasons or developing the few characters they have introduced.
They've cut all that 'boring' stuff out for bigger and longer action scenes
Oberyn had a cool fight scene, all his other scenes put together probably didn't last as long though.
Its hard to give a rats ass that hes been killed and watching it with 2 people who haven't read the books they just didn't follow who the hell Doran Martell was supposed to be and couldn't remember his paramour (cant remember name) from the previous season because she had half a dozen lines in total probably.
That entire storyline gets little or no attention and isn't developed enough to hold their attention.
The best and most interesting parts of this book imo opinion were -
the iron isles, dorans plan and the general feck ups that happen with it and what was happening around river run with jaime and lady stoneheart and their somewhat inevitable meeting.
What the tv show is left with is ... a few funny lines from tyrion, possibly some nice fx with the dragons and their new and improved dorne storyline which looks pretty ropy to me.
