A masterpiece of Spanish cinema..., 22 October 2012
Author: Rabbit-Reviews from Åland Islands

After big summer blockbusters, I think it's time to turn to a more thought-provoking European movies, and Mientras Duermes is a perfect choice. We have seen a multitude of Spanish movies that are excellent but somehow they don't reach any of the viewers and instead rot in the video stores (I guess they still exist...). What is fascinating (fascinating, this movie form is alive) about them are the plots and general ideas that are so whacked out and original that it's mind boggling. And lets be perfectly clear, these are not some straight-to-DVD movies with small budget and amateur actors, but a full-bloodied cinema masterpieces, with phenomenal actors and immaculate scripts. Immediately after watching Mientras Duermes I checked out what other movies did this talented crew created and Celda 211 was my first choice. I haven't watched it yet, but it seems like a damn fine movie.

I was talking about the originality and the pureness of the ideas in European cinema, and if you remember a couple months earlier I reviewed El Habitante Incierto, another phenomenal Spanish movie with a great script. Sleep Tight or Mientras Duermes, is a Spanish movie and I implore you to see the original version in Spanish as with any other movie that has a dubbed version, no matter how good the dubbing is, it's still not the real thing. One more thing about this movie is very disturbing and that is the sympathy for Cesar that I felt throughout the movie, although I maybe shouldn't. The suspense, the twists, the acting... I could go on and on telling you how good this movie is and how the atmosphere has that special vibe, that space-time continuum thingy captured, so every time you decide to watch it, you will relive it...

You probably noticed that the half of the review space has gone in some gibberish and not a word was said about the actual movie, and the reason for this is that I am afraid to say almost anything because it might ruin your viewing experience. I dived into this, now already cult, movie without any informations and was amazed, and so far everyone that have seen it had the same reaction. Some scenes where Cesar is trying to avoid detection are nerve-wrecking and so intense that I felt like I was going through it all. But still, here's something to keep you going: César works as a janitor in a building and is pretty much disappointed in life. He has no friends nor a girlfriend, no interests and nothing to make him happy, just his menial work and the smiling faces of other people who seem to be doing just fine. One of them is Clara, a beautiful girl living in the same building. Soon she becomes a subject of obsession for Cesar and to what degree this goes is up to you to find out...
