I don't think you are being quite fair to Into the Blue. Okay, I guess it's not your cup of tea, but it did have a plot and everythign that happend could is pretty feasable. Here is some of what Ebert had to say about the movie: "This description sounds dry and abstract, but the movie is juicy with fun. I'm trying not to tell you too much about what happens, because one of the pleasures of "Into the Blue" is that it develops as a narrative, not as a series of action scenes, and the characters don't mindlessly hurry from one impossible stunt to another but weigh their options, advocate opposing strategies and improvise when they get in danger." "The opening scenes are deceptive. The Jessica Alba character seems to have wandered over from the Sports Illustrated swimsuit issue, or maybe she thinks she's in a video. Then the plot kicks in and she gets a lot to do while still looking fine in a swimsuit. She also looks surprisingly sweet after the stripper she played in "Sin City." Scott Caan, like his old man, James Caan, does a good job of playing a persuasive jerk, and Paul Walker is intriguing in the way he has his standards but can be talked out of them. People actually change their minds during this movie; in most action films, they're issued with an identity in their first scene and limited by that identity for the rest of the movie." ""Into the Blue" offers modest pleasures. It is not an essential film, but if you go to see it, it will not insult your intelligence, and there's genuine suspense toward the end. It is a well-made example in a genre that has been cheapened and made routine. There's evidence the filmmakers spent more time talking about the characters and story than about how special effects would allow them to cheat on the narrative logic. And at the end of the film, there are some small surprises about who has survived and who has not. Usually you can predict the final head count at the end of the first act. "
