I really like this movie and it is one of the only good horror movies on netflix in my opinion, however something about it really bothers me. The idea that you might drown by being held in the barrel for 2 minutes is dumb. Even if you pass out, you would still be alive and brain damage doesn’t set in until about 3 minutes. Also, Amy would have had brain damage but she had a fair chance at surviving the 4 minutes underwater, because most people die at around 4-6 minutes without oxygen
