I don't want to be a downer but Lift drives me insane. I don't find her goofy act cute at all. I find her quite irritating.
Some of the interlude characters were a little dull but there are some interlude characters who are incredibly interesting, so it doesn't balance out so to speak but makes reading the interludes a positive experience.
I got a little irritated at all the Bridge 4 characters getting their little 'breathing in stormlight for the first time' and there 'you got this bro' moments. But on a reread I really enjoyed them. I think the 1st time I was just really eager to follow the story and see what happens. On the second reread I could fully appreciate the character building scenes.
