Anyone who watched Justified when first aired would know that, unlike shows like Mad Men where the story runs across episodes and seasons, with Justified, like shows like Bonanza, each show is its own confined story. Not a criticism. Just an observation.
The casting of Justified is amazing. If you watched Mod Squad, you will be stunned to see what Linc looks like now. Similarly, if you watched Ferris Bueller, you will be stunned to see his best friend now.
Bottom Line: If you have seen Justified, you know how good it is. If not, you've got a real treat in store.
