Great, but yet very disappointing movie

Rating: 5/10 (9 August 2015)

This is the very first review I make for a movie, at least in any official kind of way...
I'm not gonna spoil the movie per say, but one may consider that what i'm about to write gives something or somethings about the movie, so if you continue to read from this point on, consider yourself warned.
Simply putting it, this movie is brilliant, up to a point. It keeps you on edge for almost all minutes of it, with one not knowing what it's going to happen, to whom or even how it's going to happen. I've watched many movies in my short life span, and I can't remember many movies that had this effect on me.
What I take from the movie is the story of a guy trying to take down a ruined justice system, after his wife and daughter were murdered, and the people responsible for it, being badly convicted for it, one being given the death sentence, and the other one, just responsible, was "set loose" over a technicality, most specifically, for being a cooperative witness.
Everything that happens in this movie, keeps you on edge, as I stated, and you see the horrifying brilliance of a man as he begins, and consequently continues his vengeance. From the begin of the movie, he plans everything to the most specific detail, and the movie is built upon his terrific brilliance, and I must say that in the movie perspective, his very good at what his doing.
For me, what completely killed this movie, was the fact that 99% of the time, we have to see that the "good VS. evil battle" ending almost always the same way, with the good winning... Not only that, but the way the movie ended, was just awful in my opinion. On one side, we have a guy that's a master mind and the very best of his business, which is, putting it shortly, killing people. On the other side, we have a counselor, that's also the best at his job, but c'mon, when on one side you have a guy that kills the way he does (and if you watched the movie, you know what I mean) and he doesn't plan for what happens in the end? C'mon Hollywood...
If this movie ended the way it was supposed to end, I would've given it a 10, but because the ending is so bad, and I can't even stress how bad the ending is, I give it a 5, because up to the end, the movie is brilliant, but as I've stated, the end and only the end ruined an otherwise perfect movie.
