O Altar

More intelligent than many horror films. Yes it is a horror film, but it is not all gore and guts. Note that it does not fall into the other end of the spectrum as just a thriller either (there is some blood). It is an original, well done production that strikes me as unlike most of the horror of 2010.

The strong points would be better acting than many films of the genre, characters that are smarter than most horror movie characters (they still do some stupid things, but they don't know they are in a horror movie), and some nice creepy effects.

If you watch it then be aware that when people are not speaking English and there are no subtitles this is intentional. There is nothing wrong with the version you are watching. Hang in there. Context will tell you what you need to know.
