I'm not sure what exactly the IMDb is doing with their "Demographic Breakdowns" lately but they are not as trustworthy as in the past.
This is a fairly decent movie, with a good level of mystery and tenseness that builds as the film progresses. It's not just the same old plot of a couple vacationing at a remote cabin & the female has had psychotic episodes in the past so now she's deemed crazy & no one trusts anything she see's or says, I mean it is basically but leads to an entirely different end. A good end.
The male lead's acting wasn't that good and the material isn't anything we have not seen before, But it keeps you guessing and surprises you at the end. This is a SOLID 5-6 in rating, give it a chance sometime, you won't be disappointed,
