I can't believe how much filler we've had this season at the expense of crucial character beats like Jaime's dream. So many pointless scenes going over the same stuff. Joffrey is getting married? Yeah, I fucking get it. Now can the plot move forward? Where the fuck even is Mace Tyrell? Well why introduce him when we can have pointless Theon torture sequences. Every week! Ones that aren't even half as interesting as the actual Reek plot in A Clash of Kings we should have had last season.
All of this is because the showrunners should've condensed the material more, ending the season on Joffrey's death or even further. ASOS is the best book in the series, but the best and the most eventful part of it starts with the Red Wedding. Which means S4 will be beyond epic.
It's been about 2.5 years since I last read ASOS, but what does Mace Tyrell actually do in the story, besides just being there and trying to look important? He's not smart like Grandma Tyrell, not colourful like Oberyn Martell and generally not that important in the grand scheme of things. I can't see him being more than guest role, mostly just sitting on the background.
Arya kills her first man a year too late
As Ayelborne pointed out, her killing someone who was responsible for the single most horrific thing she had ever seen in her life made much more sense than killing some random guy in Harrenhall.
To be honest, I never was a fan of Arya in the books (or Starks in general, for that matter), but Maisie Williams being so great in her role and working so well with everyone she gets paired with made me like her TV version. Her being older than in the book also works better.
But the dumbass casual audience will still whoop and declare every episode as "Epic win!" if tits are shown.
The critical and ratings success of this show has nothing to do with tits. It is a well written and well done show based on good source material. It is more faithful to the source material than 99% of adaptations I've seen.
For the more recent example - have you seen the World Without End mini-series, an adaptation of Ken Follet's novel about 14th century English town? Those who did the adaptation didn't even get the date of the Black Death plague right, that's how much they didn't care. None of characters even remotely resembled their book counterparts. The acting ranged from bland to extremely bad. It looked very cheap. But maybe I'm just spoiled by GoT and expect the same production values from every period show.
Wait, they didn't include Jeyne in Season 1!? Fuuuuuuuck.
What for? Why include a very minor character who will be needed in the late S4 at the earliest, when no one will remember who the hell she was? Or would you prefer her having invented scenes of brothel training and such for three whole seasons, just like Theon had in this one?
