Adding to some others' points about the flimsy ending:
1) the police release a just killed body for return to mainland within hours, not to mention they let the killer fly off. The entire resort would have been in lock down for at least 24 hours while they investigated the events. 2) our bride reconciles with a terrible groom, who incidentally just killed someone (did she not get the news? Or does she really not give a damn about that? Seems like it might matter. Even randoms at the airport had heard the news). 3) the family doesn't jump off the plane to chase down their son. Not going to happen like that. Why does Hollywood repeatedly bale on any semblance of realism when going for their preferred endings?
