There is a movie I've seen with some sort of apocalypse. This could be a B movie and I think it's pretty recent, but I'm not sure. The only scene I remember is people trying to get higher in a building as water floods the area/world? I remember seeing some sort of bad creature in the water, but I don't remember what. It's not much to go on, but I can't get it out of my head. Can anyone tell me the name of the movie?
