Not necessarily unpopular, but Elantris was my least favorite Sanderson book. (There's a couple I haven’t gotten to yet, like White Sand and Legion). I know it is his first published work and all that, but it just isn’t super great. I had to struggle through a lot of it and will only reread it if there's a sequel. I just think it could’ve been done better. (Yes, I know he's learned since then, but just Mistborn compared to Elantris is like night and day to me).
Mini rant over, continue with your lives.
