I dunno man. I really liked Return of the Crimson Guard. The Crimson Guard are sort of an unknown in Erikson's work. You know they exist, and you know the Avowed are pretty bad ass. Outside of that and their vow against the Malazan empire, you don't learn much about them in Erikson's ten books. Learning more about their inner workings and their hierarchy was enough for me to thoroughly enjoy that one.
I didn't care much for Blood and Bone or Kellanved's Reach, but otherwise enjoyed Esslemont's stuff.
Dense, and reluctant to actually explain things. Book one's whole conflict is resolved by an Azath, which doesn't get an actual explanation until like book seven. So until you make it to book seven, book one's ending is, "The bad guy entered the city, and then a house burst out of the ground and ate him. The end." For that matter, be honest, how many of the various races in the setting could you actually physically describe with any degree of specificity? Maybe four, of the twenty-some-odd races that show up?
Loved the series, but I wouldn't have minded if they had explained things a little more than not at all.
This gripe of yours is the thing that drew me into the series and world more enthusiastically than I had previously been with other fiction. The first chapter of Gardens of the Moon drops you into the aftermath of a massive battle, where sorcery has wreaked havoc across the battlefield. Instead of explaining the ins-and-outs of the Warren-magic system, Erikson has the characters discuss things among themselves without a care in the world about whether the reader understands what they're talking about or not. The characters aren't there to explain the intricate details of the world around them to the reader.
This is where I start when I talk to others about how this series is different than anything they've read before, and why it is so good. The storytelling is so different than what most readers are used to. The characters don't sit around and talk about things that they already understand in detail for the reader's benefit. Instead, they live in the world and talk about things to one another as if that person understands what they're talking about. It's up to the reader to piece together the information given to them, to try to more fully understand what's happening in the story.
Yea, the bad guy entered the city and got swallowed by a house that burst from the ground. But at that point in the story, the reader is still wondering what a Jaghut Tyrant is. What's up with the T'lan Imass vs Jaghut thing? Are all Jaghuts tyrants, is tyrant a title or a descriptor? Whoa, whats with the red dragons and that dark elf dude turning into a black dragon, why are they so willing to drop everything to fight this thing? These questions are what draw the reader in.
When Anomander first shows up in Baruk's room, and Baruk feels a massive pressure on him, Erikson could have explained it in detail: Baruk was just chilling when a hundreds-of-thousands-years-old dark elf showed up in his room, carrying a sword with the souls of all those slain by it trapped in a magical realm and attached to a wagon which they are pulling away from a gaping maw of Chaos, and Baruk was like "bro ur giving me a headache!" Instead you're left with more questions than answers, and with a desire to learn more and continue reading.
I've rambled a bit, but I guess I'll sum it up by saying this: Yea, they could've explained things a bit better. If they had, though, it may not have been as engrossing. The first two Kharakanas novels answer a lot of questions about the origins of things, but thus far also create more questions. I'll read every book published in the Malazan world by both Erikson and Esslemont. I love this world and these books.
