I will agree that Mistborn is the sort of series that can pull the most jaded mainstream reader into the fantasy genre. Sanderson has a writing style that can appeal to the masses, his character and plot development are spot on.

The comment you made about Vin being "mentally disturbed" sort of threw me. As I read the series, my perception was more of a girl who was simply a product of her environment - a desperate-yet-clever child of the streets. Always watching her back, keeping her head low when necessary, and wary or everyone. She did a lot of growing up in those three books, and Sanderson portrayed it wonderfully.

You asked at the end of your review how Sanderson's works compare with Robert Jordan's. As a reader who tried desperately to like WoT, but ultimately abandoned the endeavor around book six, I feel there is very little compare. Where Jordan is meandering and tedious, Sanderson is focused and engaging. By the time I quit reading WoT I was fully convinced Jordan had, for all intents and purposes, given up on trying to create a cohesive body of work (reviews I've read of Sanderson's work on finishing the series implies he's done an amazing job of tying things up). I'm sure there are readers out there who enjoy them both, but I doubt it's for the same reasons. Whether or not one is willing to read the entire series, simply because they're a Sanderson fan, is up to the individual, (I wasn't able to do it).
