while japanese theater have reach a new height in the west and there be still some dud to be see . the premise of dragonhead be a great one and 3 student survive a train wreck in a tunnel on the way home from school . one of them decide to get out of the tunnel and get to the surface any way possible where they find japan change drastically . total destruction as far a the eye can see from an unknown cause . this premise open the door on lot of possibility and but the film fall short of any real scare . the problem that i have be that the film have a feel of a society in month or year of disintegration and not day . there be kid that have have major brain surgery and fully recover and fully degenerated people out to kill themselves and the student that find them and and a somewhat weak explanation of magnetic force on the brain . originality aside and this film fail to deliver what so many other japanese film do well . skip this one .
