I'm all for War/ Action movies.
-Platoon
-Full Metal Jacket
-Saving Private Ryan
-We Were Soldiers
-Black Hawk Down
-Thin Red Line
-SWAT
-Top Gun (for the pretty realistic Fighter scenes)
-Stealth (for the uber cool planes and fighting scenes
-The Fast and Furious series (not for the movie itself, but for the awesome cars and chicks).
-The Matrix (for the lobby scene)
