The first mistborn book is a bit on the nose, it comes across as a bit of a weird mix of teen romance meets classic teen fiction rebels vs fascist empire. Probably not Sanderson’s best work as it is on the older side now, but it gets way way better after the first book (as many Sanderson series do). The Wax and Wayne mistborn books are awesome, so don’t give up after the first one!
Haha it was mostly the Crokus centred part I got that impression from, plus a few other elements like edgy Anomanded Rake. I got that impression a bit with the daru cabal plot but it is probably too harsh a criticism for most of the book.
