Most of the Star Wars films are known and loved for their action packed, multi-threaded, climactic ending sequences. In Return of the Jedi, there was a large space attack happening above the forest moon of Endor, along with an epic duel between Father and Son with lightsabers and taunting by an evil menace. The battle above Endor was paired with a battle on the surface of the planet that succeeded due to the brave actions of the Rebel Alliance soldiers (and those pesky Ewoks.) Had any one of these battles gone in favor of the Empire, the galaxy might have been a very different place in the following years.
