If you're considering buying this movie, it's because you've already seen it,so I don't have to comment the movie, beyond the fact that, for me it's a marvelous psychological drama (4/5 or even 4.5/5). The thing that I want to discuss here, is the fact that the encoding of the movie in blu-ray is really poor(I think it has the same problem on DVD). There's a lot of « minor bugs » and « minor freezing » between scenes or even in the middle of a scene. I've already sent back the 1st copy I had... and when I've watched the movie with my 2nd copy, I still had the same problems... So if you really want it, buy it on Blu-ray, because it seems to have less bugs on this format. BUT If you like the movie, but it's not a must for you, it would be better not to purchase the movie on blu-ray or DVD.
