The World's Greatest Detective?

I know that this is a Smallville blog, but people have been making articles on Bruce Wayne, so I figure no one will get mad. I love the Batman Begins and Dark Knight movies don't get me wrong, but I was really dissapointed on how they portrayed Bruce as being a little dull. I mean in the comics he's the greatest detective in the world, and in the movies he's...well...He's just not not the sharpest guy. I mean I'm 15 years old and even I know what submarines use for navigation lol. Was anyone else disappointed by this or am I alone?
