This was NOT a terrible movie; here's why.
I'm only 19 years old, so I understand the a**holes who come in and automatically push aside my opinion. Actually, I don't. What's with this condescending crap I see on these forums everyday? Moving on. I've been watching movies my entire life, I like the deeper meaning movies with fantastic plots and acting like Secretary, American Beauty, Seven, Sergeant York(just showing my range in films) and tons of other classics. But I see absolutely no reason in admitting when I've enjoyed a film that really isn't all too great but looking at it from a realistic(note I said realistic, not believable) point of view and putting myself in their shoes makes it a wild and enjoyable ride. I'm aware a lot of you watch films and critic every second of it, almost forcing yourself to hate every movie until proven otherwise. I'm not talking to you group of people, hope is already lost. I'm speaking towards the reasonable, open minded people who realize an enjoyable film experience doesn't need Academy Award or "sleeper indie hit" attached to it.
The jumping into the water without checking the ladder thing was a completely normal thing to do. You call them idiots, but did YOU think about the ladder until they themselves realized it was missing? I thought not.
Ever lock your keys in the car?
Ever forget to lock your car?
Ever forget to turn the stove off?
Ever forget the water is running in the tub?
Sure all these aren't life threatening, but I'm just trying to get my point across. It's simple, THEY FORGOT. You're on a yacht, you've been drinking, you think it's cool to jump off the boat into the water. It's really not that mind blowing that they forgot the ladder. Even if they did, you'd think a yacht would have a back up plan.
Now I do agree they could have easily come up with more creative ways to get on the boat, especially with the part they had to hold on too, but we had to have a movie didn't we? Ok, so I didn't justify the entire film but I really didn't see a reason too. My main point is that the reason for them ending up in the water wasn't terrible, and if you actually think about what a terrifying experience it would be if you were in their shoes, it's actually scary as hell. 'Course you need a little imagination for that.
