Montage from Call of Duty 4: what the big deal?

Someone has decided to create a montage to his favourite game, and that is Call of Duty 4. I have to say that the montage footage does look good, however I have never got into the game and I have to wonder what the big deal is.

If my brother heard me say that, he would drive the 120 miles just to kick my butt. If I gave the game a chance I guess I would enjoy it, however I love racing games so you can keep your Call of Duty 4.
