I totally agree! I remember the first time I ever saw one of the huge 'Super' Star Destroyer command ships in The Empire Strikes Back, and being only 6 or 7 years old at the time; I was in awe!
I like the actual name of a so called Super Star Destroyer which is the Executor Class Star Dreadnought, which it really is a Dreadnought, the weapons those things have are sick and to think the RA could kill one at the battle of Endor, my goodness.
I remember sitting in the theater with my girlfriend watching the opening scene of Star Wars, as the Star Destroyer comes in and FILLS the screen:

Great opening scene.
