When Should I Move On to the Next Book?

I loved Brandon Sanderson's Reckoner trilogy. Everyone keeps recommending Mistborn as some of his best work. So I started reading it eventually. The first book in the series is the one currently in progress, because I for some reason just never read more than one book at a time.

Don't worry, I'm not gonna spoil anything. I've read something like 50 pages, probably more. I don't have it near me to check.

The thing is that I find all the characters quite boring. And unrelatable. I'm not really rooting for any of them. The prelude text to each chapter has also been enough for me to figure out things that are supposedly twists later on (someone accidentally confirmed my theory). It just doesn't suck me in. I could put the book down in the middle of a chapter without thinking about it more that day.

Somehow I feel a little guilty. Everyone who usually have the same taste in books as I have said that it's so great. It feels like I owe it to them, and the book, to read and enjoy it. I keep wondering if maybe the next chapter is the one that will hook me. I just can't really muster the interest to find out any more.

Maybe I should just leave it and start another book. Are Jane Austen novels any good without zombies?
