This one was a nice surprise! I really appreciate little films like these. A very tight Spannish psychological thriller, very stylish and well thought out (both story-wise and technically, with great shots and angles). A young woman (doctor) gets accepted to go and work in a mental institute. Things are not quite what they seem in there, and it doesn't take long before patients start to die. The first half of the movie indeed moves rather slow. And after that, things get really weird (the films of David Lynch come to mind). But in the end you get a plausible explanation, so the movie itself never derails. When you look at it afterwards, then you might figure out the explanation in the end yourself. But "Hipnos" does a very good job to keep the truth hidden until the final scenes. I say this one is certainly worth seeing. And yes, I'm generous in my rating, but there's just too many real crappy films on DVD out there. This one's absolutely not one of those.
