Hopefully this helps.
I really don't know why you would go into a science fiction movie based on a fictional galaxy in the distant past that revolves around the use of magic known as the force and expect a realistic display of physics. You baffle me.
"Holy crap dude! Did you see that ship burst into a ball of flames? That's soooooo unrealistic as there is no oxygen in space! Is this screenwriter retarded? What now? Hyperspace? They're going faster than the speed of light? Haven’t these idiots heard of Einstein's theory of special relativity? HELLLLlloooo!"
If you're going to nitpick the movie, talk about the shitty dialogue and wooden acting. The physics in the movie are supposed to be unrealistic.
good point, good point. and yeah, the acting was pretty horrid at parts, as for the dialogue. hah, i actually laughed out loud when darth vader was like 'NNNNNNOOOOOOOOOOOOOO!'
