I watched both
Cave of Forgotten Dreams and
Under the Skin relatively recently. The documentary was extremely interesting, and well worth the watch. Highly recommended.
Under the Skin....I figured I would chime in, as I am the resident Trippy Movie(TM) guy to some extent! I liked it a while lot, but the issues Golgot mentions are certainly there. The film is already relatively short, but I think they might have been able to knock another 15 minutes off the final run time. I hadn't heard anything about the film when I saw it, so nothing was spoiled for me, but I would have trouble calling the final reveal a twist, per se. A twist tends to set you up in such a way that you think something is one way, but it turns out to be another entirely. In Under the Skin, the viewer just doesn't know what is going on, and isn;t given much to go on until the final scene of the film, when things snap into focus. That said, the ending is still murky at best. Oh OK, so she was a _______ the whole time. The reveal has crossed my mind as one of several ways things could have shaken out, and one of the ideas that crossed my mind happened to be correct. Right away, I was reminded of Sayles
Brother from Another Planet, because her character sort of wanders around in the same way, saying very little, and just sort of observing in between dates.
So anyway, my mind was sort of already going that direction, and I just enjoyed the hyper real the flick was put together. it was ALMOST an amazing film, but as Gol mentioned, it falls short in some ways.
Fair warning, it is kind of depressing in a few different ways - not a fun film.
Good reviews, Gol!
