Terderness is not a thriller, it is a drama with suspense, if you don't get it, then you don't. It is an indie, different, and not a happy one, not by far. It reminds me of the Korean film Seom (The Isle), although it is not as brutal, just as sad. People in it, very well portrayed all in all, are desperate, trying to be anything else than they have to be. It is rare to find this slowly moving film with such strong emotions beneath the surface, specially when the problems are so far off, at least an American one, they are use to be about people finding themselves. This film is about trying to lost oneself. It deserves to get noticed, although I can't imagine normal people liking it. But if you like such films as The Isle, Underground, Funny Games, it is a must.
