Almost perfect

Rating: 9/10 (26 July 2014)

To me, because I was fore-warned that there is a big twisted ending by some douchebag, well the same douche that recommended me to watch so I guess half a douche? So I saw that plot a mile away. Which kill the surprise. There are entirely too many sign of it along the way, even though admittedly director tried to hide it and did a pretty job at it.
Action sequence was disappointing. It's like he got this ability of been a good fighter, but used none of it. I guess the argument is it doesn't help with the plot. But I just wish to have seen a bit more action in this.

I've a lot of interest in that prison system. Why are rest of them locked up for? You don't have that many solitary prisoner without some crazy story before, during and after the imprisonment!!
It would've been way cooler if the penthouse elevator door closed and room became another prison with that background sound play non-stop forever, until the guy kill himself (probably take all but 15 seconds)
The bad guy shot himself, which was another let-down. Sick bastard like that should've waited until the guy go crazy in that room and kill himself before the end.
