The first book was very bad, the second book was actually much better and I enjoyed it (I assume the editing was much more extensive), but the third book was again barely readable and put me off the series.
I might start it again at sometime in the future, because it is definitely something I would otherwise enjoy. I think I read somewhere that the third book might actually have been written before the second, which gives me hope.
And what I love the most is that he planned ten books rather than needing to shoehorn in extra books after planning a trilogy.
I absolutely adore the huge cast of characters and the fact that you kinda need to pay attention to get the most out of it.
I've been reading a lot since I was very, very young, and have gotten better at it. To be fair, I do have to stop myself from skimming, which is fine with most books but definitely not Malazan.
And also, I probably forget most of it after I finish it, until I read it again.
The audiobooks are 390h total (16 days 5h according to Wikipedia). If your commute takes an hour each way, that’s less than a year even if you only ever listen to it while commuting.
Maybe that's what separates it from other series though.
I would say it needed a series re-edit. First book or two are really differently paced from the end; those two should probably get bulked up a bit, and pulled fully into the final story lore.
Then the series needs a trim down, probably like 33% of pages. It's possible some of the story arcs need to be moved around as well for better readability.
I have just specified like a decade of hard labor, I know. :)
With that done, I think Malazan could be considered one of the all-time great fantasy series. As it stands, it meanders too much at times, and it falls into a sort of military + fantasy sub-genre which I think lessens the impact of the overall story -- it really is an epic RPG-style quest involving hundreds of characters with a (mostly) satisfying finale.
