Aquaman- the movie

would be a terrible idea lol. how can he save the day, if all the bad things happen on land, and his powers only exist in the sea? who invented this guy anyway? what a lousy super hero. now, if say, you put Aquaman in the titantic, well then it might be a happier story. but he doesnt just sit around waiting for sinking ships, how depressing is that. what DOES aquaman do all day?
