The movie had fantastic effects, but the plot didn't really make sense, and the movie's pacing felt awkward and disjointed. The "science" was frustrating. I would have liked more screentime for the other women in the movie rather than an emphasis on Lena's affair and marital problems.

Many people viewed movie together, and we all understood it differently.

The movie could have more action and better explanation of the story line.

Overall it was pretty confusing. Wasn't keen on the gore aspect. Felt like a lot of things weren't explained in enough detail. Beautifully filmed though.
