saw the Swedish version of this
it was really good. i'm torn actually. i kind of felt like the remake was actually a little better. like he took the best things from the original and made them better (thought the kids were better in the remake). but then at the same time he ripped off so much from the original. obviously it's a remake, but so much was straight out of the source material (even down to the way shots were set up, stage direction etc..). the fact that the Swedish one was the original i guess automatically makes it better.
but i did like the flash forward thing with the hospital at the beginning in the remake. changing the structure added more tension. also the scene with the guy hiding in the back seat of the car was pretty epic (in the remake)
both good. have to hand it to the o.g. though
