Shouldn't this movie be considered horror ?

Yes. Christabella (Connie Nielsen) had a pair of horrifying foreign objects wedged beneath her flesh where you would expect to see a pair of breasts. When she was lying on her back they looked like a pair of snow globes under a sheet. They looked like they were about to burst through her skin and attack someone at any moment: Attack of the Silicone Monsters. That will no doubt give me nightmares for weeks to come.

I would definitely consider it part of the horror genre. Did someone tell you it wasn't?

Horror? I dunno, Supernatural Thriller maybe.

Good film though, one of Keanu’s better efforts.

definitely horror.

we talking Satan here people ..!
