Watched "Black Water", a crocodile film based on the same events as "Rogue" was. While it is more true to reality than Rogue, it's still very loosely related to the real events. In reality, 3 guys went quadbiking, went to wash their clothes in a river, one got swept away, the others went after him to help, got swept about a kilometre downriver, were attacked by a crocodile, one was killed, and the other two spent the night in a tree before being rescued by the police.
In "Rogue", there's almost no relation, since it's about a group of tourists stuck on a tiny island, with the tide coming in, besieged by a giant crocodile, and has insane things like a guy fighting it with a big stick (and winning).
In "Black Water", a woman, her sister and her sister's husband are on holiday, and decide to go on a boat tour of a river. Their guide mentions that there used to be a lot of crocodiles in the area, but there aren't any more. The enter a swampy area, with loads of trees in the water, and the boat is capsized by a crocodile, and their guide is killed. The manage to get up a tree, but no one knows where they are, so they have no hope of rescue. The rest of the film is them trying to get out.
It was a pretty good film. The fact that the water IS black and you can't see below the surface builds tension very well, as you can't tell if the crocodile is even there half the time, and often it turns out that it isn't, so when it is, there's more of a shock. However, having only 4 cast members, and killing one off in the initial attack does not allow for many kill scenes, which leads to people escaping death rolls with unbelievable minor injuries.
It's also a bit slow in places, with a lot of scenes of people shouting at each other arguing what to do next, with no excitement during these scenes, as they're all safe in the tree, so there's no threat from the crocodile. The fact that it all takes place during the day, apart from one brief night scene (again, in which everyone is perfectly safe), does make it a bit less scary, too.
Still enjoyable. 7/10.
