Don't let the rating fool you.
I just watched this and it's very entertaining for a low budget romp. It's got decent acting...and for once...a good story. There's a big twist you absolutely cannot see coming that makes it all worth it. It's no way a 4.7.
I'd give it a solid 7 but I'm going to give it an 8 because the lead actress was so good in it. Music was solid, FX were decent...not the absolute best...but far better than some other low budget efforts.
