I think it matches because, while it is a western-influenced story about one man’s unorthodox methods of taking care of business, Justified is a full-blooded western about about one man’s unorthodox methods of taking care of business.
Now, I promise that this Star Wars reference is not the only reason I have to relate it to The Mandalorian.
I remember when Justified was first about to premiere on FX and the network, known for its signature brand of unique promotional material for its series, ran an ad that saw its protagonist, Raylan Givens, mentioning Han Solo’s fatal meeting with Greedo at the cantina before he shoots a bar patron who was clearly not a good man.
