I picked up Mistborn on a lark- based in large point by the written praise of Robin Hobb (an author whose work I greatly enjoy. I have not yet read Elantris, the author's first work. So, with an open mind, I picked up Mistborn...
And was greatly impressed! I consider myself a fan of Jordan, Hobb, Martin, Erickson, Williams and have recently enjoyed the works of R. Scott Bakker. I can now add Brandon Sanderson to the list.
The product description, and some of the other reviews, give pretty accurate assessments of the story and plotline.
So, with that in mind, it's worth highlighting a few of the strengths and weaknesses of his story- with an eye toward hoping the weaknesses are resolved come book 2...
* Nice world-building
* Good story arch/plotline
* Original "magic" system
* Prose/dialogue/elocution: Several passages of inter-character discussions were ... just.. too explanatory. I (personally) try to gauge when reading items whether people in an actual conversation would speak the way an author portrays. And, unfortunately, especially after "major" plot points, I felt some of the conversations between characters were just... too long- near soliloquy's vs. being dialogue. Again, this is a style point and a personal tick of mine.
* "Generic" characterizations: Much has been made of Vin's ability to swiftly learn allomancy; however, both she and Kelsier were the most fully-drawn characters. Other characters- Marsh, Breeze, etc- were more shallowly drawn. Again, I'm not talking about the need for Jordanian descriptions, but, within the context of a 3rd person-limited perspective, I'd like to gain a bit more insight into how the current person (aka Vin) feels/knows/sees of these other important secondary characters.
So, take that as you will, but, no matter what: buy and enjoy the book. For an author's second work, it's fantastic. I look forward to reading Elantris, and, also, book 2 of this series.
