I enjoyed this movie, but you need to be wary about how it's being described as a drama- horror-thriller. It's far more a drama than thriller, and I can't think of any horror elements in it at all. I don't want to give any of the movie away, so I'd like to describe what might make it more likely that you'd enjoy it.
Passengers concentrates on character development and primarily on Claire Summer (Anne Hathaway), a therapist who suspects she's discovered a cover-up while treating the survivors of an airplane crash, but also deals with her awakening to the reality that she's sacrificed too much personal life for her career. Her loneliness is as important to this movie as the mystery she's trying to unravel.
I liked Hathaway in this role. I wouldn't normally have thought of her as playing the part of a professional woman with two Masters degrees, as she usually conveys beauty and warmth instead of intellect. However, she's portraying a young academic on her first real-world case and she's convincing when she spouts the predictable, psychobabble an inexperienced therapist would likely spout. I also liked her relationship with her mentor Perry (Andre Braugher). The only weakness in the film might be insufficient scenes exploring her loneliness. It's the reason she gets involved with Eric (Patrick Wilson) but it should have been set up better. I'm not sure we're entirely convinced she would have gotten involved with him. Her isolation from family and friends should have been developed more.
It's not a great movie, but I did enjoy it, and I don't find the complaints I've heard about the movie credible; that it's slow and derivative. North Americans have developed such short attention spans, "slow" often only means there's not a car crash every few minutes. Yes, it's derivative, but so is Eagle Eye, a film currently doing very well at the box-office, which is obscenely derivative, but it doesn't seem to bother anyone since it's loaded with car crashes and other mindless action. (Eagle Eye is also appallingly dumb!)
If you're looking for a drama with some elements of suspense which takes it's characters seriously, then I would recommend it.
