Lesson: How a possible good movie becomes a spoil-sport

Rating: 7/10 (17 February 2010)

It seems to be Death Sentence+SAW+Die Hard3 (and many, many other thrillers) Lets not discus about which part of this movie is similar to which other movie, lets take it on its face value, i.e. its the most original idea.
A few goons storms into our hero's home and kills his wife (Memento? and others) and daughter. Though one of the attackers got death penalty, another got away by pleading guilty. Hero doesn't like it, and decides to take revenge. After 10 yrs, he manages to kill the other person, gets caught (why in nude, I could not get), later proves a point on how imperfect and fragile the law is.
Till this part the movie is commendable and thoughtful.
And from this part the decline starts, he somehow gets addicted with killing people. The criminal lawyer of the convict, the judge (as same as Dark Knight), even a whole law farm. The kind of sympathy the character was able to generate at the start of the movie, starts fading (for me at least). The rest is insane and climax is sh1t.
If from the beginning of the movie he was shown as a psycho killer, I would not have hated this movie so much. I hated it only because it had a very good potential to be my fav. but it just didn't justice to its start.
This movie is a very good example of how a movie should not be made.
