This is your average Thriller - 4/10 with me needing to take a point off for the horrendous ending that will have you scratching your head as to what actually happened. There is clearly a decided ending to this movie so it's NOT supposed to be ambiguous. The writer took the time to create an outcome to a Cliffhanger like moment at the very end. The only problem is that the storyboard would have taken maybe 5 minutes of film and apparently, was only given about 30 seconds so rather than tell the end of the story and the outcome so that people can follow, you get quick random flashes of what I am guessing the outcome is chopped up only these flashes are intertwined with the present cliffhanger scenes so you can't seem to figure out if the person is dreaming or if the person died and this was what he/she was thinking about or if the scenes are from the future and really did happen, etc.. It's just a mess and it leaves you feeling unsatisfied and a little annoyed that the movie waited so long for the big TWIST and then subsequent Action after the twist to occur since clearly they ran out of time or something - just inexcusable.
Now, the actual movie... It's about a couple, Marla and Parker (Carlson and Babcock) enjoying their honeymoon on a remote island who, to Marla's surprise are joined by Parker's sister Ria and her husband Cameron who Parker has invited. Things get crazy when a group of villains (Val, Angel and Joani) break in and the core 4's lives are in danger. A category 3 storm is coming forcing the villains to take shelter and hold the group hostage. The rest of the movie takes place inside the home with the dynamic between the villains and the victims with elements thrown in to keep the suspense high like an attempted poisoning and the lights going out allowing the victims to attempt to get away and hide.
Of course there is a TWIST at the end followed by the horribly executed ending. The movie wasn't bad, although the ending sure was, BUT even with a good ending I'd just give it a 5/10 - maybe 6 b/c it wasn't anything great.
