I don’t even know where to begin.

never saw it. Atom has zero customer service, my account was used by someone else

very Interesting Story And Excellent Cast!!

Previews looked great, actual movie not too good. Lacking more horror and not enough 9 tailed fox.

people who say ; it's dumb or 2 stars or its boring* obviously dont have a complex education. I can't it till gets released on bluray.

It was entertaining and Sandra Ohh was great

Back story could have been more detailed and the ending could have shown so-hyun change

it just wasn't a good movie the acting was really good but the movie itself was just boring, I kept falling asleep not scary at all and the plot is so bad and predictable

Umma turns out to be a “quality” thriller that can’t be bothered to get down and dirty and scary.

Movie Nation

Despite Oh’s solid fear-filled performance, Amanda’s inevitable possession seems to take forever in an 87-minute movie, and the inevitable maternal-love-powered dispossession seems rushed.

The film bizarrely takes what could have been a touching and powerful drama about the traumatic family ties that bind (and occasionally choke) and attempts to refit it as a straightforward, if mostly low-key horror exercise chock-full of scenes involving various things popping up out of the darkness with numbing regularity.
