would you even want a Justified movie or miniseries?

It is pretty heavily suggested that Wynn Duffey ended up with a significant amount of that money.

Admittedly, I did lose track of the money, there were two large duffel bags when Markham delivered it, then as I recall we see Ava and her uncle struggle with getting one bag up the mountain? It has been a while since I have seen it, but later we see her with a back pack with 1MM.

We also see Boyd try to unsuccessfully did up a bag. He digs up Grooves instead, but then the camera leaves Boyd, so who knows, maybe he found a bag later? Maybe only Ava knows where it is? Maybe Zacharia hid a bag, and since he is dead no one knows.

The 1MM went back to Markham before he died. You are right, nothing definitive is stated about the 9MM. However, we know Ava called someone for help and that person got her out of Harlan. Raylan theorizes it was Duffey, and since we are meant to accept that Raylan is almost always right, I think that is probably what happened, albeit off screen.

Suffice it to say, Duffey wasn't going to help anyone for free, so he did end up with something. Still, it could be he got the remaining contents of one bag with another still out there? Four-Five million would be a big payoff by itself.

Several other things were left open as well. I wondered if the four year time jump was done to get the show to the present day just in case they came back for a made for FX movie or a short run series. The show started in 2010, but covered under 2 years of time. The time jump in the finale put it back into the present, so they could easily pick it back up in real time.

Also, when Boyd surrenders, he flatly tells Raylan that he will get out of prison someday. After the time jump Ava echoes the same sentiment to Raylan that is why she never wanted Boyd to find out about his son.

Can you imagine Boyd's surprise to find out that Ava is alive? His elation if he found out he had a son? Someone like Boyd would see a child as his redemption. Then there would be the hot rage toward Ava and Raylan for keeping the boy a secret. It would be a powerful scene. There is no one better than Goggins to pull it off.

It is like the writers are taunting the audience saying that the story isn't finished yet.

Finally, all the regular cast lived. They can bring back any character they want (Tim, Art, Rachel)- and I hope they do, even if I am being delusional.
