If I gave the Swedish version a 10-10, I give the American version, 9-10.  I disagree with this San Francisco Chronicle article  that says basically, it’s like the Swedish version but better. A bit of a superior attitude, don’t you think?
The Swedish version is darker. It holds onto creepy moments that much longer and doesn’t spell absolutely everything out for you.’But OMG, but I have to read subtitles..I think my head is going to explode.’
Both films are great but I still prefer the Ikea version.
