Nice find, thanks! The comparison between the Rebels and real-world militia is almost spot on, I'd say. At times, they almost come uncomfortably similar to terrorists (though that's more specific to Saw's group on Jedha). It's hard to root for them in a way because they're not the heroic group of the Original Trilogy - they're a barely organised conglomerate of people who hate the Empire!
I get a little more out of it each time I watch it. Last time, it was "the Empire is actually dangerous, not evil-but-vaguely-incompetent"!
