I enjoyed the movie, I knew it was based on a real life tragic event but didn't know what it was so I wasn't sure what the bad event was until I saw the movie.
The crash scene near the beginning was pretty good and got my attention for the rest of the movie.
Don't do any reading about it until you have seen the movie and then go and read about the real life facts later.
Some reviewers say it reminded them of the X Files, so if you like that show maybe it will be worth seeing.
Why fly non stop when you can connect
