What are your thoughts on the American remake of "The Girl with the Dragon Tattoo"?

I passed on it in the theatre because I wasn’t really sure what it was. Dumb move on my part because when I rented it, I was blown away. I’m eager to see the other two installments. I saw that they’re making an American version. Normally, I can’t stand remakes. But, this kinda made me a little more irked than usual. With the foreign remake track record, why are they doing this? For this to work it will be nothing like the original and that makes this film a waste of money. Okay, I’m ranting a bit now, sorry. I just don’t get why they’re doing it. Thoughts?
