After reading all the low reviews here I watched this thinking it was going to be a stinker, however I was pleasantly surprised that it was enjoyable and kept my attention from start to finish. Acting and special effects were good (anyone who has a fear of flying like myself could relate to the atmosphere that was conveyed) and the killer was somewhat a surprise. I can't believe reviewers are griping about the size of the plane or that the stripes on the pilots were incorrect, it's a movie about ghosts on a plane for heaven's sake and you want accuracy? It's all about entertainment and yes this was fun and kept my interest.
I am disappointed in reviews here lately, either they give 10's for stinkers or unwarranted 1's and for this reason I would take most reviews here with a grain. You will know within the first 10 mins if you will enjoy a movie so don't let unfair reviews spoil it, give it a go.
