OK so what is this film rated this high for??

Rating: Null/10 (15 January 2005)

I've watched this film after hearing a tremendous amount of positive reviews and applauses from audiences. When I watched the movie, I thoroughly enjoyed it. All the action moves were realistic, photography turned out to be magnificent, and the actors put a lot of effort to bring up all the mis en scene to the truly competent standard. However, what is the point of the film when a guy takes revenge to someone who tortured him by having him live in a jail like room for 15 years? Yea Yea Yea, the main character should have been more careful with his words, thus there was a reason from the first place, why Dae Su got into that room. OK NOW..... What is the difference between this film and Kill Bill when looking with philosophical view? Come on! Shall I call old boy a series of 'more creative revenge process' ?
