I watched it.
Unsurprisingly, Star Wars was #1 on their list of the most influential movies. Of course ABC's parent corporation couldn't pass up the chance to get in a shameless plug for The Force Awakens. It was interesting seeing footage from the two movies intercut, albeit cropped to fill the 16:9 tv frame.
Forgot to pay attention to this, but I don't remember noticing any obvious-to-the-layman SE shots aside from the Alderaan and Death Star explosions. It seemed like they were focusing more on character and dialogue anyway, but it's nice they at least tried keeping it to what people actually saw in 1977.
Pretty sure it was the existing Lowry transfer.
The interview clips with Ford were interesting. I don't think I'd ever heard about him telling George "move your lips as you type, it might make it easier for us somewhere down the line." Unless that was just his cleaned-up-for-tv version of the "you can write this shit, George, but you can't say it" story.
