The casting agent gets an A+ for this stinker: Foster, Sarsgaard, Bean, and more. But even this stellar cast can't pull off the miracle demanded by this subpar script/screenplay. The intro is engaging and promises intrigue; a good whodunit. The first significant conflict really grabs you; Foster sells it like a pro. And that's when the movie ends.
Foster spends the next fifty or so minutes bleating in increasing shrillness to whoever will listen to her story about her missing daughter while at the same time alienating those same people, and everyone else on the plane, with her increasingly annoying antics. There are no red herrings. There is no suspense. The movie builds like a suspense movie should, but does so in all the wrong places. Instead of layering a bit of information here and a bit of information there building a cohesive plan toward the intended ending with some red herrings to divert the attention of people like me, the director instead layers one incredulous situation upon another in increasing magnitude that blasted me out of my suspension of disbelief early on and never got it back. So when the movie finally got around to ending, I found that I didn't actually care because neither outcome was actually supported by the body of the movie.
Sure, everything was explained at the end of the movie, but there's two points here. First, it's like explaining to your parents how the dents really got in the car years after lying about it in the first place. Secondly, a movie should be explained throughout the movie; it's called storytelling. If a movie has to be appended by an explanation, it wasn't really a movie, was it? It was a three minute TikTok video of a narcissist going on about a crazy lady on a plane and a twenty second response by airline management stating that everything is OK.
Don't waste your time, move on to something entertaining. Or suspenseful. Or both.
