in fairness, they should have checked the time.
i think i saw a watch on Daniel. i know this happened in real life, and its terribly sad. but the tour group should have given them a specific time to be back, rather than giving an estimate of how long theyd be diving. but they should have kept track of the time!!
still tho, i enjoyed the movie... (not in a sick morbid way!)
