Actually deserves about 7.9 - 8.3 rating.
I really liked this movie but unfortunately the mainstream is too narrow minded to fully enjoy this ride. Travolta gave one hell of a performance - even better than in reservoir dogs. But people dismissed it as stupid. Oh my how stupid will the very same people feel, when this movie reaches cult status in about 1-25 years.
So I offer to all the haters - forget your prejudice, get the blu ray, pump the volume rad to the max and enjoy this undoubtedly amazing scy-fy piece. Reading a bit of Kafka' and Geothe' beforehand wouldn't hurt. You're welcome ;)
