So this was the first Sanderson book that I read and it came highly recommended by more than one friends. The book is okay. I liked it but there are certain things missing from the story (more on this later). The story in itself is great, the idea is fantastic. Burning metal and gaining power from them. I loved the idea. It is amazing in that sense, the whole world made up of Allomancers and Mistborns.
Now every great story needs a great story teller. Sadly I don't think Brandon Sanderson is that person. His writing lacks the grace and poises required in the language to write a epic. In the entire book there was not one single exchange between the characters which is worth remembering. Not one paragraph to which you would look back and think, 'wow that was some amazing writing'. My friends who have read both A Song of Ice and Fire and the Mistborn series are of the opinion that Mistborn is even better than the epic written by RR Martin. I cannot see how they say that. To me it makes no sense. Though Martin is slow he is awesome in his writing. Sanderson is fast and plain. Martin forces you to care for the character, so far I barely had any feelings for the protagonist of the novel.
In short I will say this, it is a good book, the idea behind it is brilliant, story is pretty good too. Just that it needed someone other than Sanderson to tell its story.
