This movie is so bizarre, it held my interest 'till the very end. The opening scenes are interesting. You see a woman getting ready, but you don't see her face as she does. For instance, you see her take a shower but can only see her body through shiny shower tiles, which distort her image. You see her looking in the bathroom mirror, but the mirror is covered with steam from the shower, and so on.
The reason for this, you soon find out, is because this woman is experiencing an identity crisis. As her true identity is slowly unravelled in this movie, it's unravelled in a very bizarre way. Her surroundings and the people in it gradually morph before her eyes. The special effects in this movie are well done and lend a creepy vibe to this movie.
As these changes occur, you're just as bewildered as this woman. It's as if she's entered some alternate universe that's meant to reveal some memories she's repressing, but you don't know what those memories are so they don't quite make sense.
When it's finally revealed at the end, it may or may not be clear to some people. The ending doesn't totally spell everything out, which may annoy some and delight others. I found it delightful because enough is revealed to help me understand her story, but there's still a tiny bit of mystery left to keep it interesting.
