Warning: This article contains spoilers from the series finale of "Boardwalk Empire."

If you tuned in "Eldorado," the series finale of "Boardwalk Empire," on Sunday night, you weren't disappointed. As the screen fades to black, the show's most popular character was killed off, reports Forbes.

HBO's "Boardwalk Empire" creator Terence Winter knows how to keep his audience captivated. Dazzling cinematography, great acting and well-done costuming made the chaotic show interesting and enjoyable, and best of all, it ended in the most satisfying way.

Actor Steve Buscemi's character Enoch "Nucky" Thompson got his in the end, and most fans agree it was fitting. There's nothing more satisfying than watching a bad guy be the cause of his own undoing.

In the final two minutes of the show, the life of Atlantic City kingpin-bootlegger Thompson came to a violent end when he was gunned down on the boardwalk and killed by teen Tommy Darmody, whose father Jimmy Darmody (Michael Pitt), Thompson's former protégé, had been shot by Nucky in the Season 2 finale, "To the Lost."

Thompson's character was based on the real Atlantic City political boss and racketeer Enoch "Nucky" Johnson, whose organization was involved in bootlegging, prostitution and gambling. Johnson did not die in 1931. In the early 1940s, he served a four-year prison term for tax evasion. Later, he was a salesman for Richfield Oil Company and Renault Winery. He died at the age of 85 in the Atlantic County Convalescent Home.

"There's the true to life version of Nucky's end where he went off into the sunset and into obscurity, but our Nucky isn't Nucky Johnson, and this ending felt like the more dramatic choice, the better choice in wrapping up his life," Winter told Deadline.

"Boardwalk Empire" was based on Nelson Johnson's book "Boardwalk Empire: The Birth, High Times and Corruption of Atlantic City." Winter said he's fascinated by the fact that America hasn't changed much since the 1920s.

"We're still debating birth control, there are guys still coming home from war, and the drug business today in many ways is what it was like during the days of Prohibition," he said.

"Boardwalk Empire" had been airing on HBO since 2010.
