Dont waste your time. Its bad
Whole movie 2 trapped sisters just argue and remember past traumas. Whole survival thing is very limited in screen time.
And there is lame ridiculous villain type of person that makes no sense.
They had a chance to make good survival movie. But their script was bad.
Watch the beginning where they get trapped. Then fast forward to last 10 minutes to see ending and you will not miss anything important.
