This movie is reasonably intelligent, has decent acting, and is engaging enough. I think the lead made some emotional missteps, more to do with the script or direction than the actress. She's supposed to be eminently likable, but when she delivers a flippant line while stepping over her friend's body, I almost turned it off.
This is for teens and older, which suits me great (in my 50s). I don't like high grit in my entertainment, and mostly watch mysteries. It's good to keep the age orientation in mind, because it has some silly parts. I sensed the hands of people who did Mr and Mrs Murder, and was right! (Do look up that show, it's wonderful.)
Not a bad way to go if you don't have anything else more pressing on hand!
