Remake or....????

I wonder whether this is a remake or just took the idea from Stephen King's Thinner
http://www.imdb.com/title/tt0117894/

Of course, the plot is different, but the basic idea is the same. Precisely because of this relationship, even at the beginning of the movie I realized the purpose of the button and how will finish everything...

The difference is that in the main role is a cool chick instead of fat man, and has more effects, that are missing in the King's movie, but his story is better...
