This is a series that I just finished, Mistborn, The Well of Ascension, and The Hero of Ages. It took me a long, long time. It was good. The story was intriguing... but long winded. I have to say if I had to do it all over again I might not do it, however I really thought the story was very original and would make a fantastic movie if done well (and apparently the rights have been bought but I have no idea if they're actually going to make it anytime soon).

the synopsis of the first book:

Set in a mist-haunted, ash-ridden world, pits Kelsier, "the Survivor of Hathsin," against the immortal Lord Ruler's 1,000-year domination of both the Great Houses and their serflike "skaa." Through Allomancy acquired in the Ruler's most hellish prison, Kelsier can "burn" 10 metals internally, fueling superhuman powers he uses to assemble rebels in a loose plan to destroy the nobility, the empire and the Lord Ruler himself. Kelsier uses Vin, a street urchin with the same Mistborn powers Kelsier possesses, to infiltrate the Great Houses' society, where she falls in love with philosopher prince Elend Venture. This mystico-metallurgical fantasy combines Vin's coming-of-age-in-magic and its well-worn theme of revolt against oppression with copious mutilations, a large-scale cast of thieves, cutthroats, conniving nobles and exotic mutants. The fast-paced action scenes temper Vin's interminable ballroom intrigues, while the characters, though not profoundly drawn, have a raw stereotypic appeal.

2 out of 5 stars (but it has potential)
