Dick Crabb. What the hell was the point of him? He takes them on a long, fruitless journey, just to reach Crab Point and find out that Sansa was never there in the first ****ing place, yet we get tons of dialogue from him and background info and such. And then, bam, he's dead and none of it mattered.
With books 4 and 5, the level of detail and background information on myriad side characters just goes crazy, and while it creates a rich and vibrant world, none of it seems to have paid off in terms of any kind of meaningful development in this story.
Like, there's a sequence with Jaime visiting these two Lannister-supporting families that are squabbling over some aspect of the siege at Riverrun. And there's this whole backstory about how the families have been bickering for generations, because Aegon the Unworthy (who is, like, 6-7 kings and over 100 years in the past) dumped one mistress from one family in favor of a new mistress from the other family. Well whoopdee****. What's that got to do with THIS story? I appreciate that Martin has created this incredibly rich, incredibly vibrant, incredibly detailed backstory and history for his universe. But at a certain point, all the "universe-building" that he does behind the scenes seems to actually slow down his novels because it inspires him to take these long journeys with active characters just so that they can lightly brush up against the history of the world.
It's like Tolkein taking 500 words to describe a decrepit dwarven-carved statute that the Fellowship walks by, or something, just because he wrote a 30 page outline for a story he never published about the character depicted in the statue. "Look. That's Horick Thunderfist. Mightiest of the Dwarven Gem Singers. The Gem Singers were a religion in the Mountain Dwarf state that eventually left due to religious persecution, and became the Slightly Less Mountainous Dwarf state, until it was annexed by the Hill Dwarf state. Horick is rumored to have kicked a cave troll in the knee, paralyzing it just long enough to lop its head off when it attacked Rubyhold 400 years ago. Horick's great grandson commissioned the construction of this statue, after he returned to the Mountain Dwarf kingdom to claim his birthright in the Merchant Guild, which he claimed through his grandfather's maternal side, leading to the ultimate defacement of this statue due to allegations that the great grandson was, in fact, an illegitimate member of the Merchant Guild, due to a revision to the Guild's charter during the reign of Thrain VIII. The Merchant Guild never recovered from the stain on its reputation.
It probably was a pretty statue before they chipped his nose off and let it grow too mossy. Anyway, on to Mordor. Only 348 leagues (and many more statues) more to go!"
