This is more a slasher film where you count down who is going to be next on the list to be crossed off - it is formula driven. That being said, Death Bell has some very good moments and the middle half brings a lot of suspense and excitement and tension, though the plot gets a bit repetitive after that so you are simply waiting to find out who is the culprit.
The plot is simple: a class full of high grade students are being held captive in their school. An anonymous person has told them they must answer all the questions he gives them or student by student will be killed.
Of course, with Asian horror films, there is usually the usual cliché's - not to say that they won't work - because they usually do. This is no exception - you have your flashbacks, a tormented past and the reflections of adolescent school kids who often make the stupid choices while in stages of panic in their predicament - I guess that is universal.
The choice of music in this film is a bit questioanble as it felt more like a high beat sort of atmosphere that doesn't work at times. The concept is interesting but at the same time the film feels more like a detective game rather than anything really scary - there are only a few moments which made me shudder - and it is mainly shock tactics that don't last for more than a few moments.
Still, it is an entertaining ride. The final payoff at the end - I admit I didn't see it coming and it wasn't too bad. Think of this film like Battle Royale meets Saw.
