Most of the time, I thought this movie was quite interesting and suspenseful, and with some good scares. The actors are good, the environment is believable, and the atmosphere has the right creepiness (at least part of the time). It also evokes some thought-provoking issues, such as "what is important in life", and "should I steal some happiness for myself or do the right thing". (About this last, I am thinking of the stewardess who has a relationship with the married flight captain, but decides to stop persuading him to leave his wife and kids.)
But towards the end it all became too absurd. The story was too muddled and it did not keep together. For instance: who "the dead guy" was and what he was up to, and what it had to do with the accident with the air pressure fall, was never really explained. Was it just a coincidence that he was aboard, or did he somehow cause the accident? The twist-ending felt like: "oh no, not that old trick again". If you have watched a few modern horror films, you can see that one coming.
