These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Foe Yay: Eddie Dane towards Tom Reagan. Actually, all of the sexual tension in the movie qualifies as Foe Yay because almost everyone in the movie is pitted against everyone else.
Fridge Brilliance: How did Tom figure he could get away with pretending to shoot Bernie without any witnesses in the woods? Because he already knew Bernie, being a chronic back-stabber, would want to blackmail Tom for that "act" of mercy. And would have to stage someone else's body when Caspar or the Dane would check for one, to keep Tom alive. Tom did it because killing Bernie then wouldn't save Leo from Caspar's war.
Hilarious in Hindsight: Hilarious in production, actually. Miller's Crossing features a venal and corrupt police force. To fit the Prohibition-era setting, a lot of shooting was done in New Orleans ... where the crew ran into NOPD officers who eagerly solicited bribes to keep the shoot running smoothly.
Moment Of Awesome: Usually 'Danny Boy' is there to heighten or foreshadow tragedy. Leo plays it while lounging around in his bathrobe when guys burst in with tommyguns in hand and their hats on their heads, he sure looks like the Sacrificial Lion. But not quite. For added Badassery, he casually relights his cigar with his smoking gun while gazing at the flaming wreckage. Also doubles as Soundtrack Dissonance.
Vindicated by History: While it wasn't particularly successful when it was first released, Time magazine in 2005 chose Miller's Crossing as one of the 100 greatest movies ever made since the inception of the periodical.
