Very strange imagery is used throughout this film, the scenes with ghostly nuns and clowns will disturb a lot of viewers. It reminded me of a low-budget version of Dario Argento's Suspiria, and the writer/producer/director thanks Argento in the end credits so it most likely was influenced by that 70's horror classic.
I wasn't very into the film in it's first twenty minutes or so, i found it really slow and it didn't seem that the story was truly going anywhere. The rest of the film takes off and becomes more bizarre with each passing minute. The unique camera angles and techniques are quite effective and add a little more than usual to this low-budget film. Just don't go into it expecting a large budget horror flick, otherwise you'll be disappointed.
The acting is a mixed bag, some of the actors did a really good job. However, some had flat performances but this didn't really take away from the overall experience.
I wouldn't say this movie really creeped me out personally (very few horror films do and i do love the genre). It does contain a very dark and brooding atmosphere throughout, plus the dark music score is quite well done. The film also leaves you thinking about what the story truly means, long after the movie has ended.
Definitely above average for a horror film and i would give it a rating of 8 out of 10.
