that movie has the real story behind it, and I find it excellent. My grandma told me story about it, she was from Chile. Penumbra is the portal you could travel with only when moon shut the sun. Wwhen I saw that movie, I was a little bit scared. I'm not a movie criticist so I would tell that it's okay on every basis, but I cant be objective because of the story above. You should watch it and see for yourself. And also, dont hate me for my bad english. I've never learned it. Hope you'll understand my review. thats all. ;) namaste
