It's... Different. Like, it's not difficult in terms of what is happening in the moment etc but more, "why are these things happening?" There's also a lot to keep track of over the ten books.
If you take Sanderson at one end, where everyone's motivations are explained out loud, often repeatedly, Malazan is at the other end, with you having to work out what some folks/God's are doing and why.
My second time through was arguably one of my favourite reading experiences of all time.
