I really don't get the point of budget complaints this far into the series; people should get it by now that this isn't LOTR. I feel like many book purists don't give the show any credit, and instead focus on what isn't being shown. Having dragons flying around in every Dany scene, or direwolves chilling in every Bran/Robb/Jon scene, or turning every battle into a massive action piece etc costs money and ultimately doesn't make the show better. I'd rather have that money spent increasing the scale of important things, like making the climax of this season more epic - and luckily the creators agree.
The books are unfilmable in a direct 1:1 ratio. We knew there would be budget issues from the get go, even with HBO. While I understand complaining when something looks legit bad (like say, Dany's wedding or the Hand's tourney), complaining that Harenhel is "not big enough" and things along those lines make no sense.
