This a beautifully sad movie about the impossibility of love. If you like movies about love and overcoming loneliness set against a backdrop of magic and darkness, then you'll love this movie. It's really hard to compare to any other movie, in all honesty. There's a great deal of sexuality in the movie, too, which also sets it apart.
The Shape of Water is set in a government facility in the 60s. The main character is a mute cleaning lady. All around her are tragic characters that are making their way through a dark world of longing and loneliness. No one feels complete in this world. Everyone is lost and trying to find their own truth... but not happiness. The marriages are dysfunctional and everyone dreams of another life. Along comes a magical creature, ripped from its world and forced into their darkness. But the magic is infectious. Soon our heroine falls for this creature that makes her feel complete. All of these incomplete characters find their purpose in this creature. Some to contain it. Others to learn about it. And the rest seek to set it free.
I really enjoyed this movie, but it is rather dark and sad. There is a bit of aberrant sexuality, so if that's not your taste, you might not enjoy this, either (full nudity, masturbation, cross-species love, etc.) Still, it's a deep (PUNS!) movie that touches many of the darker aspects of our society. There's fear, hatred, struggles with sexuality, loneliness, blind power, politics, and more! But it is a dark and sad movie, so it might not be for you.
